Influence of the Second Phase Particle’s Size Distribution on Grain Growth Based on Computer Simulation
Based on cellular automata, a model of simulating grain growth is established to study the effects of the second phase particle’s size distribution on grain growth. The simulation results show that the second phase particles in the matix pin the grain boundary and then inhibit the grain growth. Different size distributions of the second phase particles have different pinning effect on the grain boundary, and the relationship of average grain size for the material with the second phase particles is RLognormal＞RUniform＞RNormal. The correlative laws obtained from the simulation is in accordance with the theoretical models.
