Kinetics of ordering for a ternary system on square lattice

The kinetics of ordering for a ternary system on the square lattice is investigated by means of the micro-master equation method in the pair approximation. The evolutions of the long-range order and short-range order parameters are calculated. There are transient ordered states during the evolutions to the equilibrium phases. The occurrence of the transient states depends on the temperature and the jumping rates of constituent atoms. The influence of the correlation and the atomic interaction are analyzed.
