Retrospective Collection

The proceedings of an International Conference "Diffusion in Metals and Alloys" (DIMETA-82, Hungary, September 1982) are related to physical metallurgy and are dedicated to researching various types of diffusion processes in metals and alloys, intermetallic compounds, amorphous metals, and heterogeneous systems. There are articles in this issue also devoted to grain boundary and surface diffusion phenomena, crystallographic defects, and novel experimental methods of diffusion phenomena study.

The presented monograph is devoted to the problem of diffusional creep of the polycrystalline materials. In monograph are reviewed chronologically recent developments in this sphere and included some theoretical models and results of their experimental verification for the prediction of the creep behavior of materials.

This edition is dedicated to researching non-crystalline materials starting from non-crystalline metals and alloys and finishing amorphous polymers, semiconductors, and various types of glasses. Readers will find here descriptions of methods to study non-crystalline materials, results of analysis of electrical and optical properties of amorphous semiconductors, and other detailed information about the structure and properties of non-crystalline matter.

This monograph is devoted to the analysis and investigation of the electrodiffusion phenomenon. The application of an electric field to a metal, alloy, or other material may result in the transport of matter as well as the flow of electrons. This phenomenon, variously described as electrotransport, electromigration, or electrodiffusion, is most commonly manifested in the separation of the components of an alloy which results from their different induced rates or directions of migration. An applied field may similarly produce In pure elements a directed displacement of vacancies or interstitials (self-transport) or different isotopes (the Haeffner effect).
