Abstract:

Diffusion in ordered alloys and intermetallic compounds has received little attention in recent years, even though it lies at the heart of many fundamental and practical problems. As opposed to diffusion in dilute alloys or solid solutions, atom movements in ordered alloys are affected by the state of order in the material. Conversely, atom movements change the state of order, either locally, leading to large diffusional correlation factors, or globally, leading to order-disorder transformations. Diffusion controls the sequence of compound formation during the intermixing of pure elements, and affects properties such as creep, hydrogen embrittlement, and stability against electromigration. These topics form the scope of this book. This book originated with the Symposium on Diffusion in Ordered Alloys and Intermetallic Compounds, held during the 1992 fall meeting of The Metals, Minerals, and Materials Society TMS in Chicago. The goal of the symposium was to bring together scientists having interests in basic and applied problems ranging from diffusional correlation factors, to effects of diffusion on microstructural evolution and on the properties of ordered alloys. The speakers and the topics were selected to match the scope of the nascent book, and the editors and authors worked together to ensure broad coverage without overlap.
