Simulation of Static Recrystallization of Low Carbon Steel by Cellular Automaton Based on Non-uniform Storage Energy Field

The model of static recrystallization of low carbon steel was established by cellular automaton method on the basis of subgrain abnormal growing mechanism underthe non-uniform storage energy field conditions, and the recrystallization processes at different deformation conditions were simulated. The results show that the bigger the storage energy, the smaller the recrystallization critical nucleation radius. Recrystallization nuclei preferentially formed on the grain boundaries and in the small grain interiors when the deformation degree was lower. With increase of deformation degree, the distribution of the recrystallization nuclei trended to homogeneous, the incubation period and recrystallization time became shorter and the recrystallization grain size became smaller. The results of simulation agreed with experimental results.
