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

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.

Linus Pauling wrote a stellar series of over 800 scientific papers spanning an amazing range of fields, some of which he himself initiated. This book is a selection of the most important of his writings in the fields of quantum mechanics, chemical bonding (covalent, ionic, metallic, and hydrogen bonding), molecular rotation and entropy, protein structure, hemoglobin, molecular disease, molecular evolution, the antibody mechanism, the molecular basis of anesthesia, orthomolecular medicine, radiation chemistry/biology, and nuclear structure. Through these papers the reader gets a fresh, unfiltered view of the genius of Pauling's many contributions to chemistry, chemical physics, molecular biology, and molecular medicine. Contents.: The Chemical Bond: Metallic Bonding; Hydrogen Bonding; Crystal and Molecular Structure and Properties: Ionic Crystals and X-Ray Difraction; Molecules in the Gas Phase and Electron Diffraction; Entropy and Molecular Rotation in Crystals and Liquids; and other papers. Readership: Chemists, biochemists, molecular biologists and physicists.

Charge density analysis of materials provides a firm basis for the evaluation of the properties of materials. The design and engineering of a new combination of metals requires a firm knowledge of intermolecular features. Recent advances in technology and high-speed computation have made the crystal X-ray diffraction technique a unique tool for the determination of charge density distribution in molecular crystal. Methods have been developed to make experimental probes capable of unraveling the features of charge densities in the intra- and inter-molecular regions of crystal structures. In Metal and Alloy Bonding - An Experimental Analysis, the structural details of materials are elucidated with the X-ray diffraction technique. Analyses of the charge density and the local and average structure are given to reveal the structural properties of technologically important materials. Readers will gain a new understanding of the local and average structure of existing materials. The electron density, bonding, and charge transfer studies in Metal and Alloy Bonding - An Experimental Analysis contain useful information for researchers in the fields of physics, chemistry, materials science, and metallurgy. The properties described in these studies can contribute to the successful engineering of these technologically important materials.

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.

Although the present edition of Fundamentals of Creep in Metals and Alloys remains broadly up to date for metals, there are a range of improvements and updates that are either desirable, or required, in order to ensure that the book continues to meet the needs of researchers and scholars in the general area of creep plasticity. Besides updating the areas currently covered in the second edition with recent advances, the third edition will broaden its scope beyond metals and alloys to include ceramics, covalent solids, minerals and polymers, thus addressing the fundamentals of creep in all basic classes of materials. Numerous line drawings with consistent format and units allow easy comparison of the behavior of a very wide range of materials Transmission electron micrographs provide direct insight into the basic microstructure of metals deforming at high temperatures Extensive literature review of about 1000 references provides an excellent overview of the field
