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 interstitial alloy AC and interstitial alloy ABC (substitution alloy AB with interstitial atom C) with FCC structure at zero pressure are derived from the statistical moment method in previous paper. In this paper, we apply the general theoretical results. In this paper, we apply the theoretical results to the interstitial alloys AuLi and AuCuLi at zero pressure in different temperatures, concentrations of substitution atoms and interstitial atoms. Some calculated results for main metal in these alloys are compared with experiments and other calculations.
