The analytic expressions of the free energy, the mean nearest neighbor distance between two atoms, the elastic moduli such as the Young modulus, the bulk modulus, the rigidity modulus and the elastic constants for AB substitution alloy with FCC structure at zero pressure are derived from the statistical moment method in previous paper. In this paper, we apply the theoretical results to the substitution alloys AlCu, AlMg, AuCu, CuZn at zero pressure in different temperatures and concentrations of substitution atoms and some calculated results for main metals in substitution alloys are compared with experiments.
