We build the theory of diffusion for FCC binary interstitial alloy under pressure based on the statistical moment method, where there are the analytic expressions of the jumping frequency of interstitial atom, the effective jumping length, the correlation factor, the diffusion coefficient, and the activated energy. In limit cases, we can obtain the diffusion theory for FCC metal A under pressure.

The theory of elastic deformation for binary interstitial alloy with FCC structure under pressure is builded by the statistical moment method. The elastic deformation of main metal is special case of elastic deformation for binary interstitial alloy. The theoretical results are applied to alloy AuSi. The numerical results for alloy AuSi are compared with the numerical results for main metal Au and experiments.

In present paper, we will present the theory of elastic deformation for binary interstitial alloys with FCC structure at zero pressure and under pressure builded by the SMM. Then, we apply this theory to study the elastic deformation of interstitial alloy AgC by combining the Mie-Lennard-Jones pair potential [14] and the Morse pair potential.
