摘要：
A two-dimensional Monte Carlo approach of phase separation in binary (A + B) alloys containing vacancies has been developed. This approach involves both swamp of atom-atom pairs and atom-vacancy (V) pairs in lattices. The thermodynamics of atom jumping, atom-atom and atom-vacancy exchange have been derived. The phase separation in both symmetric and asymmetric alloys has been simulated. Based on the present approach a normal dynamics of phase separation has been revealed. It has been found that the concentration of vacancies in the lattice has a marked influence on kinetics of phase separation.
