Grain growth and nanomaterials behavior at high temperatures

Abstract

Current developments in kinetic and thermodynamic stabilization of grains in NMs-based metals, alloys and HMPC at high temperatures are generalized and discussed in detail. Special attention is paid to a possible quantitative estimation with using the regular solution approximation by considering both inner regions of nanograins and their interfaces. Recent data on abnormal grain growth are also considered. Practical application examples concerning bulk and film/coating objects are given and some unsolved problems are presented.
