Electron theory of metals textbook for advanced undergraduate students of condensed-matter physics and related disciplines.
Now in paperback, this comprehensive book is the first text devoted to the problem of understanding the electrical properties of metals and alloys. Dr Rossiter, well-known for his work on the electrical resistivity of alloys, has written a book which blends results and theory, but does not rely on a strong grounding in quantum mechanics. After an introduction to the basic ideas, the concepts of atomic and magnetic correlations and their microstructural consequences are explained. Later chapters then deal with the effects of such correlations on electrical resistivity. Examples and applications of the concepts derived are given in discrete sections, allowing the uninterrupted development of theory for each specific problem, and enhancing the value of the book for a wide range of readers from theoretical and experimental solid state physicists to metallurgists and materials scientists. Anyone with an interest in the electrical conduction process or in the application of resistivity measurements to the study of alloy configuration will find this essential reading.
This book is a broad review of the electronic structure of metals and alloys. It emphasises the way in which the behavior of electrons in these materials governs the thermodynamic and other properties of these conducting materials. The theoretical treatment proceeds from a wave mechanics approach to more sophisticated techniques for the description of the properties of metals and alloys.
It is well known that the density of molecular hydrogen can be increased by compression and/or cooling, the ultimate limit in density being that of liquid hydrogen. It is less well known that hydrogen densities of twice that of liquid hydrogen can be obtained by intercalating hydrogen gas into metals. The explanation of this unusual paradox is that the absorption of molecular hydrogen, which in TiFe and LaNis is reversible and occurs at ambient temperature and pressure, involves the formation of hydrogen atoms at the surface of a metal. The adsorbed hydrogen atom then donates its electron to the metal conduction band and migrates into the metal as the much smaller proton. These protons are easily accomodated in interstitial sites in the metal lattice, and the resulting metal hydrides can be thought of as compounds formed by the reaction of hydrogen with metals, alloys, and intermetallic compounds. The practical applications of metal hydrides span a wide range of technologies, a range which may be subdivided on the basis of the hydride property on which the application is based. The capacity of the metal hydrides for hydrogen absorption is the basis for batteries as well as for hydrogen storage, gettering, and purification. The temperature-pressure characteristics of metal hydrides are the basis for hydrogen compressors, sensors, and actuators. The latent heat of the hydride formation is the basis for heat storage, heat pumps, and refrigerators.
A Quantum Approach to Alloy Design: An Exploration of Material Design and Development Based Upon Alloy Design Theory and Atomization Energy Method presents a molecular orbital approach to alloy design that is based on electronic structure calculations using the DV-X alpha cluster method and new alloying parameters obtained from these calculations. Topics discussed include alloy properties, such as corrosion resistance, shape memory effect and super-elasticity that are treated by using alloying parameters in biomedical titanium alloys. This book covers various topics of not only metals and alloys, but also metal oxides, hydrides and even hydrocarbons. In addition, important alloy properties, such as strength, corrosion resistance, hydrogen storage and catalysis are treated in view of electron theory. - Presents alloy design theory and the atomization-energy method and its use for the fundamental understanding of materials and materials design and development - Discusses, for the first time, the atomization-energy analysis of the local lattice strains introduced around alloying elements in metals - Illustrates a simplified approach to predict the structure and phases stability of new alloys/materials
