Cellular Automata Simulation of Grain Growth under Consideration of Zener Pinning

Abstract:

Based on cellular automata, a model of simulating grain growth is established to study the effects of the second phase particle’s size and volume fraction on grain growth. The simulation results show that the smaller is the volume fraction of second phase particle, the finer is the grain of pinned matrix, and the pinning force of bigger second phase particle is stronger than that of smaller one. The correlative laws obtained from the simulation is in accordance with the theoretical models.
