Abstract

A pair interaction model applying the Bragg–Williams approach is presented. The formalism is given in a general form; ternary ordered compounds with different crystal structures and all possible point defect types are considered. Some applications are discussed. The Bragg –Williams approach is an easily applicable formalism that leads – proper use supposed – to accurate predictions concerning thermodynamic data as well as defect concentrations.

Keywords: Intermetallic compounds; Point defects; Thermodynamic properties; Ni1–xAlx; Fe1–xAlx
