Abstract
A model is proposed for representing microinhomogeneities of disordered alloys as cubic structural domains. The concept of an effective atom introduced in this article made it possible to express the relation between property and composition in terms of property parameters of nearest atom pairs, the domain size, and the short-range parameter of the first coordination sphere α1. Using as an example the concentration dependence of the Young modulus, the thermal linear expansion coefficient, and the magnetic anisotropy constant we have determined the property parameters of atom pairs and the composition dependence of α1 and of the domain size of disordered alloys of the Ni1-cFec, system (0≤c≤0.25).
