ABSTRACT

A model based on the calculation of conditional probabilities has been used to gain further insight into the study of energetics of Na-K and Ga-Zn liquid alloys. The model refers to as four atom cluster model enables us to observed feature of these alloys. Our calculations yield for both alloys, agreement with the experiment about the concentrations at which segregation occurs in both alloys.also the degree of segregation in Na-K is larger than Ga-Zn.

Keywords: Ordering Energy, activity, chemical short-range order, Four-atom cluster model.
