Single-site mean-field approach to thermal defects in binary ordered alloys

Abstract

A single-site mean-field approach for the concentration of thermal defects in a binary intermetallic AB compound is proposed, which is a modification of previously existing Wagner–Schottky-type models. A numerical investigation of the model is done for the case of thermal defects in NiAl.

Keywords:
