Study on diffusion theory for substitutional alloy AB with interstitial atom C and BCC structure under pressure

Abstract

The free energy of interstitial atoms, the nearest neighbor distance between two interstitial atoms, the alloy parameters for interstitial atoms, the diffusion quantities such as the jumping
frequency of interstitial atoms, the effective jumping length, the correlation factor, the diffusion factor and the activated energy and the equation of state for substitutional alloy AB with
interstitial atom C in a BCC structure under pressure are derived using the statistical moment method. In limited cases, we obtain the diffusion theories for the substitutional alloy AB, the interstitial alloy AC and the metal A.
