Book Description
Phase diagrams provide scientists and engineers with basic information of fundamental importance both for scientific research and for the development and optimization of materials. Collections of such diagrams are accordingly extremely useful, especially when the data on which they are based have been subjected to critical evaluation. The series 'Ternary Alloys' provides concise and - as far as published data allow - consistent phase diagram descriptions of complete categories of ternary systems e.g. Ag-X-Y or Al-X-Y. The representation of the equilibria of ternary systems in dependence of temperature results in spacial diagrams whose sections and projections are generally published in the literature. In 'Ternary Alloys' phase equilibria are described in terms of liquidus projections, isothermal sections and, in cases where the tie lines lie in the sectional plane, in terms of vertical sections (pseudobinaries). Data on invariant equilibria are generally given in the form of tables.

Book Description
This book contains 18 invited contributions to the first Inter national Symposium on Order-Disorder Transformations in Alloys+. They cover the major aspects of this group of phase transformations. Although structural order-disorder transformations have been investigated for over 50 years the invited papers, the research papers - whose titles and authors are listed in the appendix - and the discussions at the Symposium have demonstrated very active continued interest and con siderable recent progress in the subject. This is true for theoretical work as weIl as for experimental studies and for the development of materials whose properties result from order-disorder transformations. + Some major national conferences on ordering were held in the USA and in the USSR in recent years; the proceedings are available in the following pUblications: Local Atomic Arrangements Studied by X-Ray Diffraction, Gordon & Breach, New York 1966 2 Ordered Alloys, Claitor's Publ. Div. , Baton Rouge, La. 1970 3 Summaries of the Proceedings of the 2nd Union Conference on Atomic Ordering and its Influence on the Properties of Alloys, Naukova Dumka, Kiev 1966 4 Atomic Ordering and its Influence on the Properties of Alloys, Naukova Dumka, Kiev 1968 5 Atomic Ordering and its Influence on the Properties of Alloys, TGU, Tomsk 1973 111 In assembling these papers it vas attempted to compile a systematic and approximately complete compendium of the sUbject.

Book Description
Volume 7 of Ternary Alloys contains critically evaluated phase diagram data for a total of 126 ternary aluminium systems. The complete set of Al-X-Y volumes will present all ternary aluminium systems which ever have had the attention of experimentalists. The systems are arranged in alphabetical order and have a standard format, allowing easy access to the required data. The following information is provided: liquidus projections, isothermal and vertical sections, reaction schemes, invariant equilibria and crystallographic data, accompanied by short descriptive texts and extensive references. All data and diagrams selected for inclusion have been critically examined and reviewed by the world's most competent panel of experts. Ternary Alloys is the result of an international assessment programme performed by Materials Science - International Services GmbH and the Max-Planck-Institute for Metals Research in Stuttgart. The compendium is the most comprehensive source of reliable data on ternary systems available worldwide. It will prove indispensible to everyone concerned with the research and development of materials, such as materials scientists and engineers, metallurgists, chemical engineers, inorganic chemists and physicists.

Book Description
Containing over 200 papers, this volume contains the proceedings of two symposia in the E-MRS series. Part I presents a state of the art review of the topic - Carbon, Hydrogen, Nitrogen and Oxygen in Silicon and in Other Elemental Semiconductors. There was strong representation from the industrial laboratories, illustrating that the topic is highly relevant for the semiconductor industry. The second part of the volume deals with a topic which is undergoing a process of convergence with two concerns that are more particularly application oriented. Firstly, the advanced instrumentation which, through the use of atomic force and tunnel microscopies, high resolution electron microscopy and other high precision analysis instruments, now allows for direct access to atomic mechanisms. Secondly, the technological development which in all areas of applications, particularly in the field of microelectronics and microsystems, requires as a result of the miniaturisation race, a precise mastery of the microscopic mechanisms.

Book Description
This book on pressure-induced phase transitions in AB2X4 chalcogenide compounds deals with one important AmBnXp material. The interest in these materials is caused by their properties. The results are discussed for three main groups of structural families: cubic-spinel structures, defective tetragonal structures, and other structures like layered and wurtzite-type modifications. A systematic analysis of the behavior of cubic (spinel), tetragonal (defect chalcopyrites and stannites) and other crystal modifications of AB2X4 compounds under hydrostatic pressure is performed. The behavior of AIIAl2S4, AIIGa2S4, AIIAl2Se4 and AIIGa2Se4 compounds with defective tetragonal structures, compounds with layered and wurtzite structures under hydrostatic pressure and the pressure dependence of the band gap, lattice parameters, interatomic distances, vibrational modes and pressure-induced phase transitions is discussed. Many of these compounds, except oxide spinels, undergo a pressure-induced phase transition towards the rocksalt-type structure. The phase transition is preceded by disorder in the cation sublattice. The dependence of the transition pressure to the rocksalt-type structure as a function of the compound ionicity and the size criterion is analyzed. At high pressures, all ordered-vacancy compounds are found to exhibit a band anticrossing between several conduction bands that leads to a strong decrease of its pressure coefficient and consequently to a strong non-linear pressure dependence of the direct bandgap energy. Theoretical studies of phase transitions in several ordered-vacancy compounds reveal that the existence of ordered vacancies alter the cation-anion bond distances and their compressibilities. The book is written for students, Ph D. students and specialists in materials science, phase transitions and new materials.

Book Description
Statistical Thermodynamics of Semiconductor Alloys is the consideration of thermodynamic properties and characteristics of crystalline semiconductor alloys by the methods of statistical thermodynamics. The topics presented in this book make it possible to solve such problems as calculation of a miscibility gap, a spinodal decomposition range, a short-range order, deformations of crystal structure, and description of the order-disorder transitions. Semiconductor alloys, including doped elemental semiconductors are the basic materials of solid-state electronics. Their structural stability and other characteristics are key to determining the reliability and lifetime of devices, making the investigation of stability conditions an important part of semiconductor physics, materials science, and engineering. This book is a guide to predicting and studying the thermodynamic properties and characteristics of the basic materials of solid-state electronics. - Includes a complete and detailed consideration of the cluster variation method (CVM) - Provides descriptions of spinodal decomposition ranges of crystalline alloys - Presents a representation of thermodynamics characteristics and properties as a miscibility gap by using the different approximations of CVM - Covers a unique, detailed consideration of the valence force field model with the complete collection of formulas
