This volume strives to give comprehensive information about the main aspects of the behaviour and limit states of steel plated structures. In following this objective, the volume presents a complete scientific background (profiting from the fact that the authors of the individual parts of the publication have personally been very active in the corresponding fields of research for an extended period of time), but also establishes design recommendations, procedures and formulae. The significance of the volume may be seen in its challenging current concepts of the analysis of steel plated structures, encouraging progress in the field, and thereby establishing an advanced basis for a more reliable and economical design.

Describes the weldability aspects of structural materials used in a wide variety of engineering structures, including steels, stainless steels, Ni-base alloys, and Al-base alloys Welding Metallurgy and Weldability describes weld failure mechanisms associated with either fabrication or service, and failure mechanisms related to microstructure of the weldment. Weldability issues are divided into fabrication and service related failures; early chapters address hot cracking, warm (solid-state) cracking, and cold cracking that occur during initial fabrication, or repair. Guidance on failure analysis is also provided, along with examples of SEM fractography that will aid in determining failure mechanisms. Welding Metallurgy and Weldability examines a number of weldability testing techniques that can be used to quantify susceptibility to various forms of weld cracking. * Describes the mechanisms of weldability along with methods to improve weldability * Includes an introduction to weldability testing and techniques, including strain-to-fracture and Varestraint tests * Chapters are illustrated with practical examples based on 30 plus years of experience in the field Illustrating the weldability aspects of structural materials used in a wide variety of engineering structures, Welding Metallurgy and Weldability provides engineers and students with the information needed to understand the basic concepts of welding metallurgy and to interpret the failures in welded components.

Physical Metallurgy elucidates the microstructure, transformation and properties of metallic materials by means of solid state physics and chemical thermodynamics. Experimental methods of physical metallurgy are also treated. This third edition includes new sections on the permeation of hydrogen in metals, the Landau theory of martensitic transformation, and order hardening and plasticity of intermetallics. Numerous other sections have been brought up to date in the light of new developments (e.g. scanning tunnelling microscopy, CALPHAD-method, diffusion in glasses, DIGM, recrystallisation). New artwork and references have also been added. Professor Haasen's clear and concise coverage of a remarkably wide range of topics will appeal both to physics students at the threshold of their metallurgical careers, and to metallurgists who are interested in the physical foundation of their field.

As more materials with specific characteristics are made available to the design engineer the need to be able to effectively combine these has been increased. Consequently joining techniques such as brazing have become increasing important and there is a greater need to fully understand the process. The aim of this text is to provide a comprehensive overview of the technology surrounding the brazing process to allow the inexperienced engineer, student or professional, to fully utilize this technology.

A frequently misunderstood technology, die casting is considered the shortest route between raw material and near net shape. For many decades, high pressure die casting was viewed as an art based upon "seat of the pant" strategies. However, many of these crude reactions actually worked because the fundamental process is quite forgiving of eccentricities. Exploring these reactions with scientific logic, Die Casting Engineering presents a broad study of each procedure in the die casting process and clearly outlines its basic science and principles. This guide is written in a reader-friendly and logical format by an experienced authority in quality and productivity enhancement, tooling design, metal feed system analysis, temperature management, and environmental regulation. While its scope is broad and covers the many facets of die casting, the book's main focus is on function, problem identification and solution, and strategic logic. Generously illustrated, it provides a comprehensive explanation of why high pressure die casting is reliable, predictable, and teachable.

With the help of metals, humankind has established and ever-progressing position in the world and, in the process, has transformed human civilization and the face of the Earth itself. Furthermore, the harmony and effectiveness of many human bodily processes depend on the marvelous effects of metals. With each passing decade, researchers bring us knowledge of new facets of the cosmos of metals in and around us. Nonetheless, despite all the achievements of chemists and physicists, the world of metals holds many mysteries. In the surrounding world, we continually encounter new deposits of metals in the Earth, and these have enabled humankind to move toward ever greater levels of civiliazation and technological advances. And in the inner world of the human body, newly discovered layers of activities permeated by metals continually arise in our consciousness. Not only do we breathe with iron, but we also need copper to form blood and cobalt to avoid pernicious anemia. As research methods become increasingly refined and subtle, we continue to discover additional metals that are in fact regular components of our bodies. We find them not, however, as building blocks in the grosser, more physical sense, but as instruments by which our human entity accomplishes important physiological activities. In The Secrets of Metals, Wilhelm Pelikan-in the light of spiritual science-discusses the significance of the classic "seven metals" and their importance for humankind as well as for nature as a whole and the Earth. He also discusses the "newer" metals as well as the virtually unknown "radiation effects of metals-the effects of which Rudolf Steiner used therapeutically. Pelikan's method here is a phenomenological one, in which he helps us try to see natural objects in the Goethean sense, as developed by Rudolf Steiner. Here is a classic text for deeper understanding metals as a whole, as well as gaining a fuller appreciation of spiritual scientific research methods in relation to the world we inhabit.

During the last decades the knowledge of the magnetic properties of the d transition elements and of their metallic alloys and compounds has increased widely. The improvement of preparation techniques for well-defined substances, the development of sophisticated measuring methods and above all the drive to obtain more insight in the origin of magnetic interactions in solids have resulted in the publication of many specific magnetic properties for an abundance of all kinds of metallic materials. The data assembled in this booklet are selected from the comprehensive compilation of magnetic and related properties of metals in the Landolt-Bornstein New Series Group III sub volumes 19a, band c. It has been attempted to include preferentially those properties which are of a basic character and which therefore are most often needed by scientists active in the field of solid state magnetism. In the field of magnetism, there is a gradual transition from the use of cgs/emu units to SI units. It was, however, not intended to represent all data in the units of one system, regardless of how nice this would have been from a systematic point of view. Instead, mostly preference was given to the system of units that was originally used by the authors whose work is quoted. Thus cgs/ emu units occur most frequently. Of colirse the user of the tables and figures is helped in several ways to convert the data to the units which he is most familiar with, see, e. g."

The production-costs of formed workpieces are in an increasing extent fixed through the costs for designing and manufacturing the tools. Nowadays, it is possi b 1 e to reduce these redundant tool-costs by app lyi ng modern numeri ca 1 simulation techniques such as the finite element type procedures. In thi s context, the basic ojecti ve of the workshop SUtoP (~imul ation of !:!etal F~rming ~rocesses by the Finite Element Method) was to determine and - especially - to discuss the level of finite-element-simulations of metal-forming processes with regard to technological utilization. On this purpose, eight presentations have been selected to focus the discussions onto the prime aspects such as: - technological aspects (bulk metal forming versus sheet metal forming), - constitutive laws (rigid-plastic versus elastic-plastic versus visko-pl- tic material laws), - coupled analysis (thermo-mechanical coupling), - kinematical description (Eulerian versus Lagrangian formulations, co-ro- tional formulations etc.), - numerical problems (incompressibility, integration of constitutive eq- tions, iterative and incremental schemas, etc.) , as well as - contact problems (friction, heat-transfer, etc.). In order to promote discussions, the audience of the workshop was limited to 50 participants. Due to this fact, we had to refuse unfortunately many app 1 i cat ions. However, we hope that these proceedi ngs - whi ch also inc 1 ude the discussions in an almost complete extent - will be a compensation for those who could not attend the workshop SIMOP-I.

Metal contamination in the environment is a persisting global issue. The metal reservoirs in the earth have declined due to society's needs and due to uncontrolled mining activities. Therefore, the idea to recover metals from waste streams has emerged. In this thesis, cost competitive technologies such as adsorption using agro-wastes and precipitation using an inverse fluidized bed (IFB) reactor were investigated, with special emphasis on the recovery of base metals. Groundnut shell showed good potential for metal (Cu, Pb and Zn) removal. From artificial neural network modeling, the performance of the sulfate reducing bacteria (SRB) was found to be strongly pH dependent; the removal efficiency of Cu and Zn in the IFB at pH 5.0 was >97%. Electronic waste is a good candidate as secondary metal resource. The recovery of Cu from computer printed circuited boards (PCBs) using biogenic sulfide precipitation was investigated as well. Using this technology, Cu could be recovered at ~0.48 g Cu/g PCBs.

Corrosion may be defined as an unintentional attack on a material through reaction with a surrounding medium. The term can refer to a process or to the damage caused by such a process. According to this general definition, materials other than metals, such as ceramics, plastics or concrete, may also be subject to corrosion (or corrode). When no particular reference is made to the material, however, it is normally understood that a metal is being attacked. It is entirely in this limited sense that the term is used in this book. There are good reasons for treating the corrosion of metals separately, apart from deterioration or decay of other materials. Since metals have a high electric conductivity, their corrosion is usually of an electrochemical nature. The chemical deterioration of electrically non-conducting ma terials, such as plastics and ceramics, is governed by other physico-chemical principles. It is necessary to devote more attention to metallic corrosion nowadays than earlier, due to 1. An increased use of metals within all fields of technology. 2. The use for special applications, e.g. within the atomic energy field, of rare and expensive metals, whose preservation requires particular precautions. 3. A more corrosive environment due to the increasing pollution of air and water. 4. The use of metallic constructions of more slender dimensions which do not tolerate corrosive attacks to the same extent as did the heavy constructions used in the old days."

The application of computer-aided design and manufacturing techniques is becoming essential in modern metal-forming technology. Thus process modelling for the determination of deformation mechanics has been a major concern in research. In light of these developments, the finite element method - a technique by which an object is decomposed into pieces and treated as isolated, interacting sections - has steadily assumed increased importance. This volume addresses advances in modern metal-forming technology, computer-aided design and engineering, and the finite element method.

This book, intended for advanced graduate students of metallurgy, explains what happens in the critical period between extractive metallurgy and solidification and subsequent processing. An important point the book stresses is that the principles are the same in the treatment of various different metals. Someone concerned with the purification of one metal may learn from results and experiences gained on other metals and alloys. The specifics of metals such as iron and steel, aluminium, and copper are discussed in examples and in problems at the end of each chapter. The book is self-contained and covers the basic thermodynamics and fluid mechanics required.
