Book Description
Bonding Theory for Metals and Alloys exhorts the potential existence of covalent bonding in metals and alloys. Through the recognition of the covalent bond in coexistence with the 'free' electron band, the book describes and demonstrates how the many experimental observations on metals and alloys can all be reconciled. Subsequently, it shows how the individual view of metals and alloys by physicists, chemists and metallurgists can be unified. The physical phenomena of metals and alloys covered in this book are: Miscibility Gap between two liquid metals; Phase Equilibrium Diagrams; Phenomenon of Melting. Superconductivity; Nitinol; A Metal-Alloy with Memory; Mechanical Properties; Liquid Metal Embrittlement; Superplasticity; Corrosion; The author introduces a new theory based on 'Covalon' conduction, which forms the basis for a new approach to the theory of superconductivity. This new approach not only explains the many observations made on the phenomenon of superconductivity but also makes predictions that have been confirmed.* Openly recognizes the electrons as the most important and the only factor in understanding metals and alloys* Proposes "Covalon" conduction theory, which carries current in covalent bonded pairs* Investigates phase diagrams both from theoretical and experimental point of view

Book Description
Bonding Theory for Metals and Alloys, 2e builds on the success of the first edition by introducing new experimental data to each chapter that support the breakthrough "Covalon" Conduction Theory developed by Dr. Wang. Through the recognition of the covalent bond in coexistence with the 'free' electron band, the book describes and demonstrates how the many experimental observations on metals and alloys can all be reconciled. Subsequently, it shows how the individual view of metals and alloys by physicists, chemists and metallurgists can be unified. This book covers such phenomena as the Miscibility Gap between two liquid metals, phase equilibrium, superconductivity, superplasticity, liquid metal embrittlement, and corrosion. The author also introduces a new theory based on 'Covalon' conduction, which forms the basis for a new approach to the theory of superconductivity. Bonding Theory for Metals and Alloys, 2e is of interest to physical and theoretical chemists alongside engineers working in research and industry, as well as materials scientists, physicists, and students at the upper undergraduate and graduate level in these fields. - All chapters completed revised to reflect developments in research since 2005 - New experimental data added to each chapter - Broadens experimental data to support the author's "Covalon" conduction theory, which carries current in covalent bonded pairs - Total of approximately 30% - 35% new and revised content

Book Description
Diffusion Beading of Materials is an attempt to pool the experience in vacuum diffusion bonding accumulated by a number of mechanical engineering works, research establishments, and colleges. The book discusses the principal bonding variables and recommended procedures for diffusion bonding in vacuum; the equipment for diffusion bonding and production rate; and the mechanization and automation of equipment. The text also describes the diffusion bonding of steels; the bonding of cast iron and cast iron to steel; and the bonding of dissimilar metals and alloys. The bonding of refractory and active metals and their alloys; the bonding of high-temperature alloys, nickel and nickel alloys; and the bonding of cemented carbides and of a cemented carbide to steel are also considered. The book further tackles the repair and reconditioning by diffusion bonding; the bonding of porous materials; and diffusion metallurgy. The text also encompasses nonmetals and their joining to metals; quality control of diffusion-bonded joints; accident prevention; and cleanliness in vacuum diffusion bonding.

Book Description
Modern Physical Metallurgy, Fourth Edition discusses the fundamentals and applications of physical metallurgy. The book is comprised of 15 chapters that cover the experimental background of a metallurgical phenomenon. The text first talks about the structure of atoms and crystals, and then proceeds to dealing with the physical examination of metals and alloys. The third chapter tackles the phase diagrams and solidifications, while the fourth chapter covers the thermodynamics of crystals. Next, the book discusses the structure of alloys. The next four chapters deal with the deformations and defects of crystals, metals, and alloys. Chapter 10 discusses work hardening and annealing, while Chapters 11 and 12 cover phase transformations. The succeeding two chapters talk about creep, fatigue, and fracture, while the last chapter covers oxidation and corrosion. The text will be of great use to undergraduate students of materials engineering and other degrees that deal with metallurgical properties.

Book Description
Hardbound. - Complete collection of phase diagrams; - Up-to-date experimental information and bibliography on thermochemical data; - Formation enthalpies as predicted by the Miedema model for binary solid and liquid solutions and compounds. The first volume in this series presents a complete collection of heat of formation data on binary intermetallic compounds that contain at least one transition metal.Both solid compounds and liquid alloys are considered. A complete table of model predictions is given for systems which lack this experimental information and the origin of the model and the accuracy of the predictions are discussed extensively. Furthermore, the authors demonstrate the applicability of the atomic model in predicting energy effects in metal science in general. When surface energies and vacancy-formation energies of pure metals and model values for enthalpies of alloying are available, one can deal with a large variety of proble

Book Description
Since the introduction of quantum mechanics, the general theory of solid state physics has developed very rapidly. To date, a number of good textbooks on general solid state physics have been written. However, research in solid state physics has become highly specialized and undertaken in narrow fields. There is thus a great need for elementary textbooks that deal in detail with the study of solids in a particular field in order to give students basic knowledge in that field. Metallic solids with an impurity, generally called alloys, are of immense importance from both fundamental and technological points of view. The pioneering work of Bloember gen and Rowland (1953) gave considerable impetus to the study of the electronic structure of metallic alloys. Serious theoretical study in this field started in 1960 and, during the last two decades, considerable success in understanding the electronic structure of simple metal alloys has been achieved. Nonetheless the theoretical study of dilute alloys of transition metals is still in its infancy. At present there are few review articles and original research papers that examine the role of an impurity with respect to the electronic structure and properties of metallic alloys. Because of the absence of an elementary textbook that presents a comprehensive account of different aspects of the electronic structure of metallic alloys, I have written this elementary textbook on the theory of the electronic structure of metallic alloys.
