This comprehensive text presents the subject of metalworking by offering a clear account of the theory and applications of metal forming processes relevant to engineering practice. It is designed to serve as a textbook for undergraduate and postgraduate students of mechanical engineering, production engineering, industrial engineering, and metallurgical engineering. The first seven chapters are devoted to basic concepts to equip the students with the background material on mechanics, material sciences and to provide them with a sound foundation in the theory of plasticity. In addition, the importance of friction and lubrication in metal forming processes is adequately highlighted. In the next nine chapters the reader is exposed to a richly detailed discussion of specific forming processes (including the lubricated metal forming processes) and new and powerful techniques are presented (load bounding and slip line field) for solving engineering problems in metal forming. The book then moves on to forming of polymers and also covers metal powder preforms, highlighting recent developments. In the concluding portions of the book, the important factors such as force, power requirements, formability and machinability in the study of individual processes, are briefly discussed. Finally, the application of computer-aided analysis in the metalworking processes has been demonstrated, being the demand in this competitive scenario. Several chapter-end exercises are included to aid better understanding of the theory.

The intention of this book is to reveal and discuss some aspects of the metal fo- ing plasticity theory. The modern theory describes deformation of metallic bodies in cold and hot regimes under combined thermal and mechanical loadings. Th- mal and deformation fields appear in metal forming in various forms. A thermal field influences the material properties, modifies the extent of plastic zones, etc. and the deformation of metallic body induces changes in temperature distribution. The thermal effects in metal forming plasticity can be studied at two levels, - pending on whether uncoupled or coupled theories of thermo-plastic response have to be applied. A majority of metal forming processes can be satisfactorily studied within an uncoupled theory. In such an approach the temperature enters the stress-strain relation through the material constants and through the thermal dilatation. The description of thermo-plastic deformation in metal forming is c- ried out on the ground of thermodynamics.

For students ready to advance in their study of metals, Physical Metallurgy combines theoretical concepts, real alloy systems, processing procedures, and examples of real-world applications. The author uses his experience in teaching physical metallurgy at the University of Michigan to convey this topic with greater depth and detail than most introductory materials courses offer. The book follows its introduction of metals with topics that are common to all metals, including solidification, diffusion, surfaces, solid solutions, intermediate phases, dislocations, annealing, and phase transformations. Other chapters focus on specific nonferrous alloy systems and their significant metallurgical properties and applications, the treatment of steels includes separate chapters on iron-carbon alloys, hardening, tempering and surface treatment, special steels and low carbon sheet steel, followed by a separate chapter on cast irons. Concluding chapters treat powder metallurgy, corrosion, welding and magnetic alloys. There are appendices on microstructural analysis, stereographic projection, and the Miller-Bravais system for hexagonal crystals. These chapters cover ternary phase diagrams, diffusion in multiphase systems, the thermodynamic basis for phase diagrams, stacking faults and hydrogen embrittlement. Physical Metallurgy uses engaging historical and contemporary examples that relate to the applications of concepts in each chapter. With ample references and sample problems throughout, this text is a superb tool for any advanced materials science course.

Monitoring and control of microstructure evolution in metal processing is essential in developing the right properties in a metal. Microstructure evolution in metal forming processes summarises the wealth of recent research on the mechanisms, modelling and control of microstructure evolution during metal forming processes. Part one reviews the general principles involved in understanding and controlling microstructure evolution in metal forming. Techniques for modelling microstructure and optimising processes are explored, along with recrystallisation, grain growth, and severe plastic deformation. Microstructure evolution in the processing of steel is the focus of part two, which reviews the modelling of phase transformations in steel, unified constitutive equations and work hardening in microalloyed steels. Part three examines microstructure evolution in the processing of other metals, including ageing behaviour in the processing of aluminium and microstructure control in processing nickel, titanium and other special alloys. With its distinguished editors and international team of expert contributors, Microstructure evolution in metal forming processes is an invaluable reference tool for metal processors and those using steels and other metals, as well as an essential guide for academics and students involved in fundamental metal research.

This book is ideal for those involved in designing sheet metal forming processes. Knowledge of plasticity is essential for the computer simulation of metal forming processes, and understanding the advances in plasticity theory is key to formulating sound analyses. In this book, William Hosford makes the subjects simple by avoiding notations used by specialists in mechanics. R. Hill's authoritative book, Mathematical Theory of Plasticity (1950), presented a comprehensive treatment of continuum plasticity theory up to that time; although much of the treatment in this book covers the same ground, it focuses on more practical topics. Hosford has also included recent developments in continuum theory, including a newer treatment of anisotropy that has resulted from calculations of yielding based on crystallography, analysis of the role of defects, and forming limit diagrams. This text also puts a much greater emphasis on deformation mechanisms, and includes chapters on slip and dislocation theory and twinning.

Metals are still the most widely used structural materials in the manufacture of products and structures. Their properties are extremely dependent on the processes they undergo to form the final product. Successful manufacturing therefore depends on a detailed knowledge of the processing of the materials involved. This highly illustrated book provides that knowledge. Metal processing is a technical subject requiring a quantitative approach. This book illustrates this approach with real case studies derived from industry.
