Higher Order Conditional Probabilities And Short Range Order In Molten Alloys

A thermodynamic model based on cluster of four atoms is considered with a view to obtain conditional probabilities enumerating the higher order atomic correlations in the nearest neighbour shell of liquid binary alloys. This has helped to discuss as how the higher order atomic correlations in liquid alloys are related to pairwise distribution. The values of order energy, activity and the chemical short range order parameter computed for Bi-Cd, Li-Mg, Cd-Mg, Cd-Ga, Cu-Pb and K-Na are presented.
