This book is addressed to all scientists interested in the use of high magnetic ?elds and in the use of high-?eld facilities around the world. In particular it will help young scientists and newcomers to the topic to gain a better understanding in areas such as condensed matter physics, in which the magnetic ?eld plays a key role either as a parameter controlling the Hamiltonian, or as an experimental tool to probe the underlying mechanism. This concerns mostly strongly correlated and (or) low dimensional systems. Rather than covering all these subjects in detail, the philosophy here is to give essential physical concepts in some of the most active ?elds, which have been quickly growing in the last ten to twenty years. Besides its role as a physical parameter in condensed matter physics, a large magnetic ?eld is essential to Electron Paramagentic Resonance (EPR) and Nuclear Magnetic Resonance (NMR) spectroscopies. The state of art of high resolution NMRin liquids and solids and high frequency EPRapplied to ?elds like chemistry and biology are also reviewed in this volume. The ?rst series of chapters is devoted to the integer and the Fractional Qu- tum Hall E?ects (FQHE) in two-dimensional electron systems. C. Glattli brushes an historical background and a comprehensive review of transport phenomena in these systems, including recent developments on the mesoscopic electronic transport at the edges of quantum Hall samples, chiral Luttinger liquids and fractional excitations.

The increasing use of powder metallurgy techniques to make an almost infinite variety of materials and products places greater emphasis on utilization of sophisticated experimental techniques. Usually research and development efforts initiate the use of newly developed equipment and analytical procedures. Indeed, the contents of this book are strongly linked to research endeavors, in both the academic and industrials worlds. However, this volume can serve a much needed function in industrial applied powder metallurgy. Although many research ers will find the contents of great value, the technical personnel more involved with production, quality control, customer services and product design now have at their dispo sal a means to learn about the potential uses of several very important techniques. With today's "knowledge explosion" the present set of papers greatly facilitates the comprehension and adoption of new procedures. If powder metallurgy is to continue its rapid rate of growth in virtually all segments of industry, then the transition of modern equipment and procedures from tools of research and development laboratories to everyday plant operations and applications must be hastened. The editors hope that this volume aids in this process, as well as assisting students and researchers by providing a ready source of up-to-date useful information.

Electrometallurgy is a broad field but it is not a new one. It was the great Faraday in the 1830s who discovered laws covering the electrodeposition of metals and its relation to the current passed and equivalent weight of the metal undergoing depo- tion. Since that time, applications and developments of his discoveries have spread to many areas of technology. Electrowinning is the most well known, partly because it embraces the process by which aluminum is extracted from its ores. In electrorefining, the impure metal is made into anode and the pure metal dissolved therefrom is deposited on a cathode. Electroplating is exemplified by its use in the manufacture of car bumpers. Finally, in electroreforming, objects may be metallized, often with a very thin layer of the coating desired. The numerous technologies vary greatly in the degree to which they are intell- tualized. Until the work of Popov et al. , electrometallurgy has been regarded as largely empirical, an activity in which there was much art and little science. This will all change with the publication of this book. Several aspects of the background of its senior author, Konstantin Popov, make him uniquely suited to the job of intellectual- ing electrometallurgy. First, he had as his mentor the great surely the leading electrochemist in Eastern Europe since the death of Frumkin. Second, he has had ample experience with the leading electrochemical engineer in America, Ralph White.

Over the last 15 years, the application of innovative steel concepts in the automotive industry has increased steadily. Numerical simulation technology of hot forming of high-strength steel allows engineers to modify the formability of hot forming steel metals and to optimize die design schemes. Theories, Methods and Numerical Technology of Sheet Metal Cold and Hot Forming focuses on hot and cold forming theories, numerical methods, relative simulation and experiment techniques for high-strength steel forming and die design in the automobile industry. Theories, Methods and Numerical Technology of Sheet Metal Cold and Hot Forming introduces the general theories of cold forming, then expands upon advanced hot forming theories and simulation methods, including: the forming process, constitutive equations, hot boundary constraint treatment, and hot forming equipment and experiments. Various calculation methods of cold and hot forming, based on the authors' experience in commercial CAE software for sheet metal forming, are provided, as well as a discussion of key issues, such as hot formability with quenching process, die design and cooling channel design in die, and formability experiments. Theories, Methods and Numerical Technology of Sheet Metal Cold and Hot Forming will enable readers to develop an advanced knowledge of hot forming, as well as to apply hot forming theories, calculation methods and key techniques to direct their die design. It is therefore a useful reference for students and researchers, as well as automotive engineers.

Stereology is the science that relates three-dimensional structure to the two-dimensional images that can be measured. The most common field of application is in microscopy, both of man-made materials (metals, ceramics, composites, etc.) and of biological tissue samples. This book covers the applications and terminology of both fields. Recent emphasis in stereology is concerned with sampling strategies to avoid bias due to directionality and non-uniformity, and these methods are fully covered. So are the classic techniques that measure size distributions, surface curvature, etc., which are widely useful but not discussed in other recent texts. Finally, most stereology is taught as manual procedures using counting and grids, but this text also covers the use of modern desktop computers for image analysis and processing to obtain and interpret the stereological data.

Fatigue of structures and materials covers a wide scope of different topics. The purpose of the present book is to explain these topics, to indicate how they can be analyzed, and how this can contribute to the designing of fatigue resistant structures and to prevent structural fatigue problems in service. Chapter 1 gives a general survey of the topic with brief comments on the signi?cance of the aspects involved. This serves as a kind of a program for the following chapters. The central issues in this book are predictions of fatigue properties and designing against fatigue. These objectives cannot be realized without a physical and mechanical understanding of all relevant conditions. In Chapter 2 the book starts with basic concepts of what happens in the material of a structure under cyclic loads. It illustrates the large number of variables which can affect fatigue properties and it provides the essential background knowledge for subsequent chapters. Different subjects are presented in the following main parts: * Basic chapters on fatigue properties and predictions (Chapters 2-8) * Load spectra and fatigue under variable-amplitude loading (Chapters 9-11) * Fatigue tests and scatter (Chapters 12 and 13) * Special fatigue conditions (Chapters 14-17) * Fatigue of joints and structures (Chapters 18-20) * Fiber-metal laminates (Chapter 21) Each chapter presents a discussion of a speci?c subject.

This second edition, first published in 1953 when the mathematical formulation of the theory of metals was substantially completed, provides a valuable survey for physicists and research metallurgists. It is a critical survey of the electronic properties of solids. A detailed index provides a useful aid to independent reading.

William Tulloch Jeans (1848 1907) was a parliamentary journalist with an interest in economics and technology. This book was first published in 1884, and comprises biographies of six men whom Jeans believed to have made significant contributions to the development of modern steel technology. The Bessemer process revolutionised steel-making, reducing the cost and allowing steel to replace the much more brittle iron in civil engineering projects such as bridges. Siemens' regenerative furnace allowed much more fuel-efficient manufacture of steel. Sir Joseph Whitworth developed a method of producing stronger steel by removing blowholes in the ingots. Sir John Brown's rolled steel was used in almost all the British navy's armour-plated ships. The work of Sidney Gilchrist Thomas and George Snelus on reducing phosphorus content in steel meant low-grade ores could be used. The combined researches of these men transformed modern industrial and engineering methods.

Christian Heinemann explores a unifying model which couples phase separation and damage processes in a system of partial differential equations. The model has technological applications to solder materials where interactions of both phenomena have been observed and cannot be neglected for a realistic description. The author derives the equations in a thermodynamically consistent framework and presents suitable weak formulations for various types of this coupled system. In the main part, he proves the existence of weak solutions and investigates degenerate limits.

This monograph describes mathematical models that enable prediction of phase compositions for various technological processes, as developed on the base of a complex physico-chemical analysis of reaction. It studies thermodynamics and kinetics of specific stages of complex pyrometallurgical processes involving boron, carbon, sulfur, tungsten, phosphorus, and many more, as well as their exposure to all sorts of factors.

First and foremost, this enables to optimize processes and technologies at the stage of design, while traditional empirical means of development of new technologies are basically incapable of providing an optimal solution. Simulation results of metals and alloys production, welding and coating technologies allow obtaining materials with pre-given composition, structure and properties in a cost-saving and conscious manner. Moreover, a so-called "inverse problem," i.e., selecting source materials which would ensure the required results, cannot be solved by any other means.

THE PHYSICAL BASIS FOR HETEROGENEOUS CATALYSIS is the proceedings of the ninth Battelle Colloquium in the Materials Sciences, held in Gstaad, Switzerland, September 2-6, 1974. It took as its theme the application of modern theoretical and experimental surface physics to heterogeneous catalysis. Progress in the field by classical chemical methods seemed to have slowed down, at a time when the need for better catalysts was particularly great. The Organizing Committee thought it might be possible to accelerate progress by the application of the powerful techniques evolved in recent years for studying atomically clean surfaces. However, the translation of ideas derived from clean single crystal surfaces with well characterized chemisorbed layers to real catalysts with high ratios of surface to mass on which reactions were taking place and requiring transport of mass and energy is a giant step, raising many questions and requiring thorough discussion by surface physicists on the one hand and catalytic chemists on the other. The 1974 Battelle Colloquium provided a forum for this exchange. As its usual custom, the Colloquium started the first day of introduc tory lectures by three distinguished scientists who have contributed impor tantly over many years to this field."

Silicon Carbide Microsystems for Harsh Environments reviews state-of-the-art Silicon Carbide (SiC) technologies that, when combined, create microsystems capable of surviving in harsh environments, technological readiness of the system components, key issues when integrating these components into systems, and other hurdles in harsh environment operation. The authors use the SiC technology platform suite the model platform for developing harsh environment microsystems and then detail the current status of the specific individual technologies (electronics, MEMS, packaging). Additionally, methods towards system level integration of components and key challenges are evaluated and discussed based on the current state of SiC materials processing and device technology. Issues such as temperature mismatch, process compatibility and temperature stability of individual components and how these issues manifest when building the system receive thorough investigation. The material covered not only reviews the state-of-the-art MEMS devices, provides a framework for the joining of electronics and MEMS along with packaging into usable harsh-environment-ready sensor modules.

This book deals with a novel and practical advanced method for control of tandem cold metal rolling processes based on the emerging state-dependent Riccati equation technique. After a short history of tandem cold rolling, various types of cold rolling processes are described. A basic mathematical model of the process is discussed, and the diverse conventional control methods are compared. A detailed treatment of the theoretical and practical aspects of the state-dependent algebraic Riccati equation technique is given, with specific details of the new procedure described and results of simulations performed to verify the control model and overall system performance with the new controller coupled to the process model included. These results and data derived from actual operating mills are compared showing the improvements in performance using the new method. Material is included which shows how the new technique can be extended to the control of a broad range of large-scale complex nonlinear processes.

In the preliminary stage of designing new structural hardware that must perform a given mission in a fluctuating load environment, there are several factors the designers should consider. Trade studies for different design configurations should be performed and, based on strength and weight considerations, among others, an optimum configuration selected. The selected design must be able to withstand the environment in question without failure. Therefore, a comprehen sive structural analysis that consists of static, dynamic, fatigue, and fracture is necessary to ensure the integrity of the structure. During the past few decades, fracture mechanics has become a necessary discipline for the solution of many structural problems. These problems include the prevention of failures resulting from preexisting cracks in the parent material, welds or that develop under cyclic loading environment during the life of the structure. The importance of fatigue and fracture in nuclear, pressure vessel, aircraft, and aerospace structural hardware cannot be overemphasized where safety is of utmost concern. This book is written for the designer and strength analyst, as well as for the material and process engineer who is concerned with the integrity of the structural hardware under load-varying environments in which fatigue and frac ture must be given special attention. The book is a result of years of both acade mic and industrial experiences that the principal author and co-authors have accumulated through their work with aircraft and aerospace structures."

In an attempt to meet the demand for new ultra-high strength materials, the processing of novel material configurations with unique microstructure is being explored in systems which are further and further from equilibrium. One such class of emerging materials is the so-called nanophased or nanostructured materials. This class of materials includes metals and alloys, ceramics, and polymers characterized by controlled ultra-fine microstructural features in the form oflayered, fibrous, or phase and grain distribution. While it is clear that these materials are in an early stage of development, there is now a sufficient body of literature to fuel discussion of how the mechanical properties and deformation behavior can be controlled through control of the microstructure. This NATO-Advanced Study Institute was convened in order to assess our current state of knowledge in the field of mechanical properties and deformation behavior in materials with ultra fine microstructure, to identify opportunities and needs for further research, and to identify the potential for technological applications. The Institute was the first international scientific meeting devoted to a discussion on the mechanical properties and deformation behavior of materials having grain sizes down to a few nanometers. Included in these discussions were the topics of superplasticity, tribology, and the supermodulus effect. Lectures were also presented which covered a variety of other themes including synthesis, characterization, thermodynamic stability, and general physical properties."

MICROELECTRONIC INTERCONNECTIONS AND MICROASSEMBL Y WORKSHOP 18-21 May 1996, Prague, Czech Republic Conference Organizers: George Harman, NIST (USA) and Pavel Mach (Czech Republic) Summary of the Technical Program Thirty two presentations were given in eight technical sessions at the Workshop. A list of these sessions and their chairpersons is attached below. The Workshop was devoted to the technical aspects of advanced interconnections and microassembly, but also included papers on the education issues required to prepare students to work in these areas. In addition to new technical developments, several papers presented overviews predicting the future directions of these technologies. The basic issue is that electronic systems will continue to be miniaturized and at the same time performance must continue to improve. Various industry roadmaps were discussed as well as new smaller packaging and interconnection concepts. The newest chip packages are often based on the selection of an appropriate interconnection method. An example is the chip-scale package, which has horizontal (x-y) dimensions,;; 20% larger than the actual silicon chip itself. The chip is often flip-chip connected to a micro ball-grid-array, but direct chip attach was described also. Several papers described advances in the manufacture of such packages.

This vohune contains the papers presented at the Adriatico Research Conference on Structural and Phase Stability of Alloys held in Trieste, Italy, in May 1991, under the auspices of the International Centre for Theoretical Physics. The conference brought together participants with a variety of interests in theoretical and experimental aspects of alloys from Argentina, Belgium, Bulgaria, Czechslovakia, France, Germany, Italy, Japan, Mexico, People's Republic of Congo, Portugal, Switzerland, United Kingdom, United States, U. S. S. R., and Venezuela. The conference was purposely designed to succinctly cover experimental and the oretical aspects of magnetic and non-magnetic alloys, surfaces, thin films and nanos tructures. The Conference opened with an overview of a select class of advanced structural materials, with a potential in engineering applications, for which the con ventional "physics" approach, both theoretical and experimental, should have a sig nificant impact. A number of papers were dedicated to the use of phenomenological approaches for the description of thermodynamic bulk and surface properties. It was clear from these presentations that the phenomenological models and simulations in alloy theory have reached a high degree of sophistication. Although with somewhat limited predictive powers, the phenomenological models provide a valuable tool for the understanding of a variety of subtle phenomena such as short-range order, phase stability, kinetics and the thermodynamics of surfaces and antiphase boundaries, to name a few."

The microanalytical technique of atom probe tomography (APT) permits the spatial coordinates and elemental identities of the individual atoms within a small volume to be determined with near atomic resolution. Therefore, atom probe tomography provides a technique for acquiring atomic resolution three dimensional images of the solute distribution within the microstructures of materials. This monograph is designed to provide researchers and students the necessary information to plan and experimentally conduct an atom probe tomography experiment. The techniques required to visualize and to analyze the resulting three-dimensional data are also described. The monograph is organized into chapters each covering a specific aspect of the technique. The development of this powerful microanalytical technique from the origins offield ion microscopy in 1951, through the first three-dimensional atom probe prototype built in 1986 to today's commercial state-of-the-art three dimensional atom probe is documented in chapter 1. A general introduction to atom probe tomography is also presented in chapter 1. The various methods to fabricate suitable needle-shaped specimens are presented in chapter 2. The procedure to form field ion images of the needle-shaped specimen is described in chapter 3. In addition, the appearance of microstructural features and the information that may be estimated from field ion microscopy are summarized. A brief account of the theoretical basis for processes of field ionization and field evaporation is also included.

This book examines rare earth elements (REEs), materials, and metals that are critical to modern life. These serve as crucial ingredients in the latest technologies including electronics, electric motors, magnets, batteries, generators, energy storage systems (supercapacitors/pseudocapacitors), specialty alloys, and other emerging applications. REEs are used in various sectors including health care, transportation, power generation, petroleum refining, and consumer electronics. The Science of Rare Earth Elements: Concepts and Applications defines these elements, their histories, properties, and current and potential future applications across a wide range of industries across the world. It also discusses the environmental benefits, such as components in electric vehicles, wind turbines, solar applications, and energy storage systems. Conversely, the book also examines the liabilities of mining these REEs.

The problem of developing metal matrix (MCM) and metal-polymer (MPCM) composite materials is one of the most important in present day materials technology, for its solution is pivotal to the development of a number of leading technologies. The development of new fibrous and lamellar composite materials with improved physico-chemical, electrical, thermal and other properties is a springboard for qualitative scientific and technological advances not only in aerospace and shipbuilding technologies, but also in mechanical, power, electronic, electrical, radio engineering, transport, construction and other industries. The volume reviews the results of research programmes ac complished in recent years by Soviet scientists in the development of composite materials based on aluminium and magnesium matrices, polymatrix composites (composite materials) with metal and polymeric matrices reinforced with boron and carbon fibres, steel wire, fibre glass and other fillers. The volume also reviews present-day physico-chemical fundamen tals and basic principles for developing and optimizing metal matrix composites, and describes the most expedient and efficient methods of MCM and MPCM manufacturing. Special attention is devoted to the issue of manufacturing MCM structural members, and their machin ing and plastic working, as well as to coupling techniques."

Metal matrix composites are making tangible inroads into the "real" world of engineering. They are used in engineering components such as brake rotors, aircraft parts, combustion engines, and heat sinks for electronic systems. Yet, outside a relatively limited circle of specialists, these materials are mostly unknown. Designers do not as a rule think of using these materials, in part because access to information is difficult as these materials have not really entered engineering handbooks. Metal Matrix Composites in Industry is thus useful to engineers who wish to gain introductory knowledge of these materials and who want to know where "to find" them. Additionally, it provides researchers and academics with a survey of current industrial activity in this area of technology.

Ordered intermetallics constitute a unique class of metallic materials which may be developed as new-generation materials for structural use at high temperatures in hostile environments. At present, there is a worldwide interest in intermetallics, and extensive efforts have been devoted to intermetallic research and development in the U.S., Japan, European countries, and other nations. As a result, significant advances have been made in all areas of intermetallic research. This NATO Advanced Workshop on ordered intermetallics (1) reviews the recent progress, and (2) assesses the future direction of intermetallic research in the areas of electronic structure and phase stability, deformation and fracture, and high-temperature properties. The book is divided into six parts: (1) Electronic Structure and Phase Stability; (2) Deformation and Dislocation Structures; (3) Ductility and Fracture; (4) Kinetic Processes and Creep Behavior; (5) Research Programs and Highlights; and (6) Assessment of Current Research and Recommendation for Future Work. The first four parts review the recent advances in the three focus areas. The fifth part provides highlights of the intermetallic research under major programs and in different institutes and countries. The last part provides a forum for the discussion of research areas for future studies.
