Abstract: In order to rationally simulate the recrystallization process of the material with secondphase particles， a cellular automata model for recrystallization of singlephase material with tiny second phase particles was created by introducing the Zener force to resist subgrain growth and the rule of cell orientation transformation of grain boundary pinning， and the recrystallization annealing process of a ferritic steel was simulated. The results show that the model fully consider the combined effects of recovery at variable temperature， nonuniform deforming storage energy， abnormal nucleation and growth of subgrain， and impeding by fine particles on recrystallization， and the simulated microstructure evolutions and their dynamics analysis reveals the same laws both in theories and in practice， that is， the smaller is particle size and the more is its number， the stronger is the effect of inhibiting recrystallization and the longer are the incubation period and the process of recrystallization.
