Book excerpt: This monograph reviews the subject of structural disorder in alloys and describes how structural information can be exploited to build sound theoretical descriptions in terms of modified Ising models. Scattering with thermal neutrons and x-rays prove to be complementary approaches to measure the weak diffuse scattering which provides detailed information about the disorder. The authors show how Monte Carlo methods are applied to determine the most realistic effective interactions among the alloying atoms. These results can be used as a benchmark for modern electronic structure calculations. Of more general interest, the limitations of scattering experiments in a determination of an interaction model, and thus also of the structure itself are discussed. Finally, simulations exhibit not only near-surface disordering due to frustration effects but also new possible surface - induced ordering phenomena. Accurate Monte Carlo simulations are used to test existing theories of wetting.

Book excerpt: At present, there is an increasing interest in the prediction of properties of classical and new materials such as substitutional alloys, their surfaces, and metallic or semiconductor multilayers. A detailed understanding based on a thus of the utmost importance for fu microscopic, parameter-free approach is ture developments in solid state physics and materials science. The interrela tion between electronic and structural properties at surfaces plays a key role for a microscopic understanding of phenomena as diverse as catalysis, corrosion, chemisorption and crystal growth. Remarkable progress has been made in the past 10-15 years in the understand ing of behavior of ideal crystals and their surfaces by relating their properties to the underlying electronic structure as determined from the first principles. Similar studies of complex systems like imperfect surfaces, interfaces, and mul tilayered structures seem to be accessible by now. Conventional band-structure methods, however, are of limited use because they require an excessive number of atoms per elementary cell, and are not able to account fully for e.g. substitu tional disorder and the true semiinfinite geometry of surfaces. Such problems can be solved more appropriately by Green function techniques and multiple scattering formalism.

Book Synopsis Order-Disorder Transformations in Alloys by : H. Warlimont

Download or read book Order-Disorder Transformations in Alloys written by H. Warlimont. This book was released on 2013-03-09. Available in PDF, EPUB and Kindle. Book excerpt: 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.
