A conference on Metallurgical Effects at High Strain Rates was held at Albuquerque, New Mexico, February 5 through 8, 1973, under joint sponsorship of Sandia Laboratories and the Physical Metallurgy Committee of The Metallurgical Society of AIME. This book presents the written proceedings of the meeting. The purpose of the conference was to gather scientists from diverse disciplines and stimulate interdisciplinary discussions on key areas of materials response at high strain rates. In this spirit, it was similar to one of the first highly successful con ferences on this subject held in 1960, in Estes Park, Colorado, on The Response of Metals to High Velocity Deformation. The 1973 conference was able to demonstrate rather directly the increased understanding of high strain rate effects in metals that has evolved over a period of roughly 12 years. In keeping with the interdisciplinary nature of the meeting, the first day was devoted to a tutorial session of invited papers to provide attendees of diverse backgrounds with a common basis of understanding. Sessions were then held with themes centered around key areas of the high strain rate behavior of metals."

The International Symposium on Shape Memory Effects and Appli cations was held at the University of Toronto on May 19-20, 1975, in four sessions over two days, as part of the regular 1975 Spring Meeting of The Metallurgical Society of AlME, sponsored by the Physical Metallurgy Committee of The Metallurgical Society. This was the first symposium on the subject, the only previous meeting at all related being the 1968 NOL Symposium on TiNi and Associated Compounds. One of the major intentions of this Symposium was to provide a forum for cross-communication between workers in the diverse metallurgical areas pertinent to shape memory effects, areas such as martensitic transformation, crystallography and thermodynamics, mechanical behavior, stress-induced transformation, lattice sta bility, and alloy development. Authors were encouraged to place an emphasis on delineation of general controlling factors and mech anisms, and on comparison of shape memory effect alloy systems with systems not exhibiting SME."

The focus of this thesis is the computational modelling of transition metal bimetallic (nanoalloy) clusters. More specifically, the study of Pd-Pt, Ag-Pt, Au-Au and Pd-Au as a few tens of atoms in the gas phase. The author used a combination of global optimization techniques - coupled with a Gupta-type empirical many-body potential - and Density Functional Theory (DFT) calculations to study the structures, bonding and chemical ordering, as well as investigate the chemisorptions of hydrogen and carbon monoxide on bimetallic clusters. This research is highly relevant to experimental catalytic studies and has resulted in more than seven publications in international journals.

Corrosion affects every industry in which metal is involved, from manufacturing machinery to transport pipelines, and it is estimated to cost the global economy trillions of dollars per year. Many of the traditional methods for inhibiting corrosion are highly toxic (such as hexavalent chromium) or do not degrade readily in the environment (such as Benzotriazole) meaning they pose a risk to human and environmental health. Much recent work in the area has gone into searching for greener alternatives that will be both safe and effective. Beginning with a look at the fundamentals of corrosion inhibition and an explanation of the concepts of green chemistry, this book discusses various types of chemical that have been tested for their potential as greener corrosion inhibitors with reference to industrial applications. Green Corrosion Inhibition is a valuable reference for chemists and chemical engineers working in both research and design and academia who want to learn more about green corrosion inhibitors, their synthesis, design, and industrial scale applications.

Five years ago, the worldwide powder metallurgy fraternity gathered in New York City to attend the first international conference devoted entirely to powder metal lurgy to take place in the United States. It was a tentative venture, entered into by the sponsors with no idea as to whether it would fail or succeed. The only assurances we had were that the metal-powder producing and consuming industries were rapidly expanding and that powder metallurgy was truly becoming one of the international sciences. The 1960 Conference was successful not only in terms of attendance and interest, but also in terms of knowledge gained. The literature had been enriched by the contributions of its participants to foster and encourage this type of world wide exchange. Thus, another such conference was held in 1965-expanded in scope and supplemented by an exhibition of the latest advances in raw materials, processing equipment, and finished products of powder metallurgy. On behalf of the Conference sponsors-the Metal Powder Industries Federa tion, the American Powder Metallurgy Institute, and the Metallurgical Society of AIME-I thank all those who participated and who helped make the 1965 Interna tional Powder Metallurgy Conference a rewarding experience and memorable event in our industry's history. Support of the National Science Foundation, which made it possible for several speakers from abroad to participate in the program, is gratefully acknowledged.

This volume, the proceedings of a 1998 international workshop, provides experimental evidence of the effects of correlation on the physical, chemical, and mechanical properties of materials, as well as the theoretical/computational methodology that has been developed for their study.

"Modern Physical Metallurgy" describes, in a very readable form, the fundamental principles of physical metallurgy and the basic techniques for assessing microstructure. This book enables you to understand the properties and applications of metals and alloys at a deeper level than that provided in an introductory materials course.

In view of the dramatically increased interest in the study of grain boundaries during the past few years, the Physical Metal lurgy Committee of The Institute of Metals Division of The Metal lurgical Society, AIME, sponsored a four-session symposium on the NATURE AND BEHAVIOR OF GRAIN BOUNDARIES, at the TMS-AIME Fall Meeting in Detroit, Michigan, October 18-19, 1971. The main ob jectives of this symposium were to examine the more recent develop ments, theoretical and experimental, in our understanding of grain boundaries, and to stimulate further studies in these and related areas. This volume contains most of the papers presented at the Symposium. It is regrettable that space limitations allow the inclusion of only four of the unsolicited papers, in addition to thirteen invited papers. The papers are grouped into three sections according to their major content: STRUCTURE OF GRAIN BOUNDARIES, ENERGETICS OF GRAIN BOUNDARIES, and GRAIN BOUNDARY MOTION AND RELATED PHENOMENA. Grain boundaries, or crystal interfaces, have been of both academic and practical interest for many years. An early seminar on "Metal Interfaces" was documented in 1952 by ASM. The Fourth Metallurgical Colloquium held in France, 1960, had a broad coverage on "Properties of Grain Boundaries". More recently the Australian Institute of Metals sponsored a conference on interfaces, with the proceedings being published by Butterworths in 1969.

This volume entitled Advanced Science and Technology of Sintering, contains the edited Proceedings of the Ninth World Round Table Conference on Sintering (IX WRTCS), held in Belgrade, Yugoslavia, September 1-4 1998. The gathering was one in a series of World Round Table Conferences on Sintering organised every four years by the Serbian Academy of Sciences and Arts (SASA) and the International Institute for the Science of Sintering (IISS). The World Round Table Conferences on Sintering have been traditionally held in Yugoslavia. The first meeting was organised in Herceg Novi in 1969 and since then they have regularly gathered the scientific elite in the science of sintering. It is not by chance that, at these conferences, G. C. Kuczynski, G. V. Samsonov, R. Coble, Ya. E. Geguzin and other great names in this branch of science presented their latest results making great qualitative leaps in the its development. Belgrade hosted this conference for the first time. It was chosen as a reminder that 30 years ago it was the place where the International Team for Sintering was formed, further growing into the International Institute for the Science of Sintering. The IX WRTCS lasted four days. It included 156 participants from 17 countries who presented the results of their theoretical and experimental research in 130 papers in the form of plenary lectures, oral presentations and poster sections.

Atomic diffusion in metals was first discovered some sixty-five years ago, and since then a considerable wealth of data has ac cumulated on diffusion in various systems. However, work prior to about the year 1940 is now mainly of historical interest, since ex periments were often carried out under experimental conditions and with methods of analysis leading to uncertainties in inter preting the measured diffusion coefficients. Data on diffusion rates are of importance in processes which are controlled by rates of atomic migration such as growth of phases and homogenization of alloys. In addition diffusion plays an important part in theories of such phenomena as oxidation, plastic deformation, sintering, and creep. A tremendous advance in diffusion studies was made possible by the availability of radioactive isotopes of sufficiently high spe cific activity after the second world war. Measurements of self diffusion rates then became possible using radioactive isotopes having the same chemical properties as the solvent material, and it also became possible to study tracer impurity diffusion when the concentration of the impurity is so small as not to alter the chemi cal homogeneity of the system. In the last ten to fifteen years the purity of materials used in diffusion studies has increased con siderably and the methods of analysis have become more stand ardized."

During the translation, the author had the opportunity to re view several chapters, taking into consideration the more recent literature. As far as possible all new theoretical concepts and experi mental data published before 1963 have been quoted and discussed under the theoretical viewpoint of this book. A new chapter "Passivity and Inhibition During High-Tempera ture Oxidation" was introduced. Section 4.8 was enlarged by a dis cussion of the transition from internal to external oxidation. The author very much appreciates the cooperation of the trans lator and of Plenum Press. Gottingen, April 1.965 Karl Hauffe v Preface The number of publications concerned with oxidation and cor rosion processes has become so copious that many engineers and scientists find it practically impossible to obtain an overall view of the growing body of knowledge and to bring order to the confusing multiplicity of experimental data. As a result the need for a compre hensive survey of the present state of research in this field has be come more and more urgent."

Aluminum P/M parts can be production sintered in various types of furnaces and atmospheres. Selection of sintering furnace depends upon economic considerations and production rates desired. Batch furnaces have lowest investment costs and are adequate for low to medium production whereas continuous furnaces are more costly but provide higher production rates. strong, well-sintered P/M parts can be obtained in atmos pheres of nitrogen, dissociated ammonia and in vacuum. Atmos phere selection depends upon facilities available within individual plants plus property requirements. Highest strengths are produced in nitrogen followed by vacuum and dissociated ammonia. Repro ducible dimensions can be achieved with proper attention to com pact density, sintering temperature, dew point and atmosphere. REFERENCES 1. J. H. Dudas and W. A.

Sintering of powder metal compacts is one of the basic oper ations in powder metallurgy. The useful properties of a machine part are obtained after considerable densification of the sintered material. Although the mechanical properties of the part depend on other structural factors besides porosity, porosity is the main factor. Usually, the practical problem in sintering is to obtain a part with the desired or permissible porosity. Thus, knowledge of the laws governing densification and its final result is neces sary to control this process in the production of powder metal parts. The laws governing densification are also important for a more exact physical theory of sintering, which is still in the initial stages of its development. Such processes as the change in the density of lattice defects and the flow of crystalline substances during sintering have not yet received a complete physical inter pretation. Analysis of the laws of sintering may provide addition al material for more complete phenomenological characteristics of these processes that will be useful for further development of theoretical concepts of the flow of imperfect crystals under small loads. Although a substantial amount of experimental material has been accumulated, generalizations are still difficult.

Since the introduction of the first commercial inductively coupled plasma mass spectrometry (ICP-MS) instruments in 1983, the technique has gained rapid and wide acceptance in many analytical laboratories. There are now well over 400 instruments installed worldwide, which are being used in a range of disciplines for the analysis of geological, environmental, water, medical, biological, metallurgical, nuclear and industrial samples. Experience oflCP-MS in many laboratories is limited, and there is therefore a need for a handbook containing practical advice in addition to fundamental informa tion. Such a handbook would be useful not only to users new to the technique, but also to users with some experience who wish to expand their knowledge of the subject. Therefore we have written this book for users in a variety of fields with differing levels of experience and expertise. The first two chapters provide a brief history of ICP-MS and discussions of design concepts, ICP physical processes, and fundamental principles of instrument operation. Armed with this background knowledge, users will be better equipped to evaluate advantages and limitations of the technique. Detailed descriptions and information for instrumental components are provided in chapter 3. Subsequent chapters deal with the practical aspects of sample analysis by ICP-MS. Whether samples are to be analysed in liquid, solid .or gaseous form is always an important consideration, and there is a wide choice of sample introduction techniques."

Semisolid metallurgy (SSM) is now some 37-years-old in terms of time from its conception and ?rst reduction to practice in the laboratory. In the intervening years, there has been a steadily growing body of research on the subject and the beginning of signi?cant industrial applications. The overall ?eld of SSM comprises today a large number of speci?c process routes, almost all of which fall in the category of either "Rheocasting" or Thi- casting." The former begins with liquid metal and involves agitation during partial solidi?cation followed by forming. The latter begins with solid metal of suitable structure and involves heating to the desired fraction solid and forming. Research over the past 37 years, and particularly over the last decade, has provided a detailed picture of process fundamentals and led to a wide range of speci?c SSM processes and process innovations. Industrial studies and actual p- duction experience are providing a growing picture of the process advantages and limitations. At this time, the conditions for eventual wide adoption of SSM appear favorable, both for nonferrous and ferrous alloys. It must, however, be recognized that major innovations, such as SSM become adopted only slowly by industries where capital costsarehigh,pro?tmarginsaremodest,andfailuretomeetcustomercommitments carries a high penalty.

The contents of this volume cover all the major activities associated with small-scale steelmaking in mini-steelworks (except Direct Reduction, on which two comprehensive volumes have recently appeared - see refs 11 & 12, Chapter 2). There is, of course, an immediate problem of agreeing on a suitable definition of mini-steelworks and the entrepreneurial nature of many businesses based on the mini-steelplant route compounds this problem. Nevertheless, as is shown by the lucid review in the opening chapter, it is quite possible to derive a working definition of a mini steelworks. The succeeding chapters deal with steelmaking in a linear fashion; a survey of raw materials supply being followed by independent analyses of arc furnace practice, casting and rolling. The volume is rounded off by a consideration of the important topics of energy costs and environmental factors. As anyone associated with iron and steelmaking well knows, the indus try is not the exclusive preserve of the metallurgist, although he plays a prominent role in its activities. For this reason, it is hoped that the level of treatment will commend the book to a wide readership. that includes non-metallurgical professionals in plant management and elsewhere, as well as industrial metallurgists. Lecturers in universities, polytechnics and colleges of further education should find this volume useful as a course reader for final year and postgraduate studies of steelmaking."

The subject of corrosion is a very broad interdisciplinary study involving many aspects of chemistry, metallurgy and chemical engineering. In recent of microbiological corrosion has begun to develop and to be years the subject recognized, and this area of corrosion is of enormous significance in relation to the behaviour of materials buried in soil, in industry in general in relation to all types of water usage, in the machining and fabrication of materials and in certain advanced technology areas such as aircraft. As new materials are developed we shall have to cope with biodeterioration of these and since these may in some cases take the form of coatings on metals the implication of this with respect to conventional corrosion processes will have to be taken into account. Indeed there is now a very strong case for considering corrosion as the "environmental degradation of materials" and for allowing this term to embrace all materials and all forms of degradation irrespective of mechanism. This article will be concerned only with those aspects of corrosion which are immediately relevant to the scope of this book. Atmospheric corrosion, mechanical influences in corrosion, i. e. , stress corrosion, corrosion fatigue, cavitation and fretting, and considerations of the effects of temperature and flow on corrosion will not be covered. The reader who may wish to extend his knowledge of these aspects of corrosion is advised to consult the standard 1 texts available.

Nickel is probably the most versatile of the metallic elements. Among alloys containing nickel are some having high corrosion resistance and others that retain excellent strength and ductility from temperatures approaching ab solute zero to those near 2000 F. Some nickel alloys are strongly magnetic, others are virtually nonmagnetic; some have low rates of thermal expansion, others have high rates; some have high electrical resistivities; some have practically constant moduli of elasticity; one has an "elastic" memory. In addition, nickel is magnetostrictive. With this wide range of characteristics, it is not surprising that there are several thousand alloys containing nickel. It is impossible to consider all of these compositions in this publication and, therefore, several alloys in each of a number of categories have been selected to indicate the properties to be expected of the group. Low-alloy and constructional nickel-containing steels have been excluded on two grounds. To do them justice would require excessive space and, in addition, their applications differ generally from these of the materials under discussion. On the other hand, nickel-containing stainkss steels have been included because many of their applications fall into the same areas as those of a number of the high-nickel alloys. Many of the compositions discussed are proprietary alloys and they are protected by trademarks. A list of the trademarks and their owners is in cluded in the appendix."

During recent years, people involved in developing new metals and materials for use in some of the rather extreme conditions of stress, temperature, and environment have relied heavily on the microstructural condition of their materials. In fact, many of the newer materials, such as dispersion-strengthened alloys, have been designed almost entirely by first determining the microstruc ture desired and then finding the right combination of composition, heat treatment, and mechanical working that will result in the de sired microstructure. Furthermore, the extremely high reliability required of materials used today, for example, in aerospace and nuclear energy systems, requires close control on the microstruc tural conditions of materials. This is clearly evident from even a cursory examination of recently written specifications for mate rials where rather precise microstructural parameters are stipu lated. Whereas specifications written several years ago may have included microstructural requirements for details such as ASTM grain size or graphite type, today's specifications are beginning to include such things as volume fraction of phases, mean free path of particles, and grain intercept distances. Rather arbitrary terms such as "medium pearlite" have been replaced by requirements such as "interlamella spacing not to exceed 0. 1 micron. " Finally, materials users have become increasingly aware that when a material does fail, the reason for its failure may be found by examining and "reading" its microstructure. The responsibility for a particular microstructure and a resulting failure is a matter of growing importance in current product liability consider ations."

Properties of alloys are determined to a considerable extent by the form. the dispersity. the composition, and the quantitative relationships of the structural components. This monograph is an attempt to present the mechanism of the formation of the structure of alloys from the viewpoint of the most modern theory of phase transformations. The metastable state is treated at length be cause there are few data in the literature up to the present time. The book concerns the conditions determining the creation of the different phases in alloys. The forma tion of crystals of different compositions and dispersities is described. The cause of different degrees of metasta bility of alloys, the mechanism of the transformation of metastable systems into the stable state, and other problems are analyzed. The most widely used alloys were investigated. The authors tend to avoid demonstrations based on cumbersome calculations and whenever possible replace them with conceptual models. Some of the problems described here resulted from discussions during the seminar of the Metal Science Faculty of the Dnepropetrovsk Metallurgical Institute, directed by K. P. Bunin. The basic experiments were made by the author in the laboratory of the Department of Metal Physics of Dnepropetrovsk State University in collaboration with E. V. Finagin, A. N. Shul'diner, E. Z. Graifer, E. . Psarev. . I. Pesetskii, V. 1. L'nyanyi and I. S. Miroshnichenko."

One of the most effective methods of increasing the wear resistance, hardness, surface strength and high-temperature oxidation resistance of metals and alloys is the diffusion satu ration of the surfaces by metals and nonmetals. For communicating and discussing the results of the numerous researches carried out in this field in the Department of PJ: tysicotechnical Problems of Materials Science, Academy of Sciences of the UkrSSR, a permanent Scientific Seminar was set up in 1961, which enjoys an ever-increasing popularity among specialists in this field. The present collection contains papers read at the Third Session of this Seminar, held on September 25-28, 1963. The compilers of the collection and the authors of the papers hope that its publication in the U. S. A. will enable American specialists to become acquainted with the main lines along which corresponding work is being conducted in the USSR. This should contribute to an ex change of scientific experience in this interesting field which is of such great practical impor tance. G. V. Samsonov PREFACE This collection is comprised of papers relating to the diffusion saturation of metals and to coatings of refractory compounds. The papers discuss current problems in the theory and practice of the production of diffusion coatings on metallic materials. A means of classifying the methods of diffusion saturation is proposed, and a new method is described for calculating the diffusion parameters in a heterogeneous medium."

Elements of Rapid Solidification: Fundamentals and Applications is the product of many years of concentrated work in the field of rapid solidification and processing. This quasi-monograph is unique in two ways. It brings together the talent of many international scientists in an effort to focus attention on all aspects of a new scientific field and it concentrates on fundamentals and practical applications. Simply stated, this book has been written by the senior students in the field of rapid solidification technology for the new generation of solid-state physicists, materials scientists, materials engineers, metallurgists and ceramicists.

The idea of this conference grew out of the rapidly increas ing volume of experimental facts. and theoretical concepts related to the problem of crystal-field effects in metals and alloys. The crystal field plays an important role in the understanding of the energetic level structure of ions in condensed matter. In partic ular, the magnetic properties of rare earth metals and alloys are strongly influenced by the crystal field. In the phenomenological theory the crystal field successfully describes the static and dynamic magnetic properties of these systems. On the other hand the microscopic origin of the crystal field in metals is not yet fully understood. However, recent years have seen some of the areas of crystal-field effects mature to the point that they should be summarized and brought to the active notice of a larger audience. In addition, a number of exciting developments have occured which deserve attention. This book contains 13 invited and 45 contributed papers pres ented at the 2nd international conference on crystal-field effects in metals and alloys held at ZUrich, Switzerland, September 1-4, 1976. Emphasis was placed on the following specific categories of interest: spin waves and excitons, soft modes and critical effects, magnetic properties, physical properties influenced by crystal field effects, actinides and valency. Because the conference was relatively small, about 120 participants, and because the topic was relatively narrow, recent work in the field could be treated thor oughly and the present state of knowledge assessed comprehensively."

/.letallography is much more than taking striking pictures at high magnifications or polishing and etching specimens in such a way that no scratches can be seen. Basically, metallography is the physical metallurgist's most useful and most used tool for studying metals. Although it is perhaps his oldest tool, it certainly is not likely to become obsolete. Rather, the continued demands that have been placed upon materials have required more detailed charac terizations of their microstructures and this, in turn, has re quired the metallographer to develop new techniques to make these characterizations. Not too many years ago, the metallographer had only optical microscopes with which to examine his specimens. Now he has elec tron microscopes, scanning electron microscopes, and a whole host of instruments which were unknown to him only a relatively few years ago. This has forced him to learn not only how to use these new instruments and how to interpret the information that they provide but it also has made him develop new techniques for preparing the samples for examination."
