Abstract

A simple statistical mechanical model based on pairwise interaction has been considered to obtain conditional probabilities for the occupation of neighbouring atoms in binary molten alloys. This has been extended to obtain simple analytical expressions for activity, free energy of mixing, concentration fluctuations in long wave limit and the chemical short range order parameter. Application is made to compute ordering energy and the concentration dependent thermodynamic properties for CuPb, NaK, LiMg and CdMg. The study reveals that self coordination among nearest neighbour atoms exist in CuPb and NaK whereas heterocoordination exist in LiMg and CdMg.
