In this paper, the stochastic modeling of a phase transition process is studied and the behavior analysis of the phase transition is performed through numerical simulations. It is supposed that thermal fluctuation and disturbance such as impurities in materials play important role in the phase transition process. So, in this paper, taking such disturbances into consideration, we propose the stochastic model of the phase transition. Phase transition of the binary alloy is generally classified into a phase separation and an order-disorder transition. By using the proposed stochastic model of the phase transition, the influence of the disturbances on the phase separation and the order-disorder transition is studied through numerical simulations.
