The method of Bozzolo, Ferrante and Smith is applied for the calculation of alloy energies for bcc elements. The heat of formation of several alloys is computed with the help of the Connolly-Williams method within the tetrahedron approximation. The dependence of the results on the choice of different sets of ordered structures is discussed. Bozzolo, Guillermo and Ferrante, John and Smith, John R. Glenn Research Center RTOP 505-90-52...

- Up-to-date compilation of the experimental data on the structures of binary compounds by Villars and colleagues. - Coloured structure maps which order the compounds into their respective structural domains and present for the first time the local co-ordination polyhedra for the 150 most frequently occurring structure types, pedagogically very helpful and useful in the search for new materials with a required crystal structure. - Crystal co-ordination formulas: a flexible notation for the interpretation of solid-state structures by chemist Bill Jensen. - Recent important advances in understanding the quantum mechanical origin of structural stability presented in two clearly-written chapters by leading experts in the field: Hafner, Majewski and Vogl. ``The Structures of Binary Compounds'' presents not only the most up-to-date compilation of the experimental data on the structures of binary compounds, but also the recent important theoretical advances in understanding the quantum-mechanical origin of structural stability. In addition to this volume, a large wall chart displaying the structure maps for the AB, ABs and AB3 stoichiometries together with the corresponding co-ordination polyhedra, has been published.The first half of the book details the successful ordering of the known experimental data in two- or three-dimensional coloured structure maps, the 150 most frequently occurring structure types being characterized for the first time by their local co-ordination polyhedra. The second half of the book details the success of first-principle theoretical calculations within the Local Density Functional Approximation in predicting the correct ground state structures of binary semiconductors, insulators and metals. The book concludes with a chapter on the cohesion and structure of solids from the more localized tight-binding point of view.

The thermochemistry of alloys has interested generations of scientists and the subject was treated in classical textbooks long ago, e.g. by Hume-Rothery, by Wagner, and by Kubaschewski and Alcock. Nevertheless, the appearance of new materials and the desire to improve traditional materials and metallurgical processes has kept up demand for more information on the thermodynamics of these systems. The advent of computing power has created new opportunities to tie various aspects and properties together, such as phase diagrams and thermodynamic functions, that are in principle thermodynamically inter related but were too cumbersome to work out before. The computer has also been a powerful tool in buUding and testing models that help to explain the underlying causes of non-ideal behavior. At the same time, these calculations have pinpointed areas, where additional and more accurate data are needed. In the laboratory, new methods, improved materials, and sophistica ted instrumentation have gradually changed the way in which experiments are done. Within the time span of perhaps thirty years, the development went from jotting down individual readings of data points to strip chart recording to automatic digital data acquisition. Scholars and students active in the field of "Thermochemistry of Alloys" convened for a NATO Advanced Study Institute at Kiel in August 1987 to discuss these developments. This book collects most of the lectures and seminar papers given at the Institute.

This conference consisted of 15 oral sessions, including three plenary papers covering areas of general interest, 22 specialist invited papers and 51 contributed presentations as well as three poster sessions. There were several scientific highlights covering a diverse spectrum of materials and ion beam processing methods. These included a wide range of conventional and novel applications such as: optical displays and opto-electronics, motor vehicle and tooling parts, coatings tailored for desired properties, studies of fundamental defect properties, the production of novel (often buried) compounds, and treating biomedical materials. The study of nanocrystals produced by ion implantation in a range of host matrices, particularly for opto-electronics applications, was one especially new and exciting development. Despite several decades of study, major progress was reported at the conference in understanding defect evolution in semiconductors and the role of defects in transient impurity diffusion. The use of implantation to tune or isolate optical devices and in forming optically active centres and waveguides in semiconductors, polymers and oxide ceramics was a major focus of several presentations at the conference. The formation of hard coatings by ion assisted deposition or direct implantation was also an area which showed much recent progress. Ion beam techniques had also developed apace, particularly those based on plasma immersion ion implantation or alternative techniques for large area surface treatment. Finally, the use of ion beams for the direct treatment of cancerous tissue was a particularly novel and interesting application of ion beams.
