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

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

Electron theory of metals textbook for advanced undergraduate students of condensed-matter physics and related disciplines.

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.

This book describes theoretical aspects of the metallic magnetism from metals to disordered alloys to amorphous alloys both at the ground state and at finite temperatures. The book gives an introduction to the metallic magnetism, and treats effects of electron correlations on magnetism, spin fluctuations in metallic magnetism, formation of complex magnetic structures, a variety of magnetism due to configurational disorder in alloys as well as a new magnetism caused by the structural disorder in amorphous alloys, especially the itinerant-electron spin glasses. The readers will find that all these topics can be understood systematically by means of the spin-fluctuation theories based on the functional integral method.

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

Theory and experiment in chemistry today provide a wealth of data, but such data have no meaning unless they are correctly interpreted by sound and transparent physical models. Linus Pauling was a grandmaster in the modelling of molecular properties. Indeed, many of his models have served chemistry for decades and that has been his lasting legacy for chemists all over the world. The aim of this book is to put such simple models into the language of modern quantum chemistry, thus providing a deeper justification for many of Pauling's ideas and concepts. However, it should be stressed that many contributions to this work, written by some of the world's most prominent theoretical chemists, do not merely follow Pauling's footprints. By taking his example, they made bold leaps forward to overcome the limitations of the old models, thereby opening new scientific vistas. This book is an important contribution to the chemical literature. It is an almost obligatory textbook for postgraduate students and postdoctoral researchers in physical chemistry, chemical physics and advanced physical organic chemistry.
