摘要
The presence of second-phase particles can influence the evolution of solidification structure and change the grain growth. In this work, a phase field model is used to analyze the effect of the size and the volume fraction of the second-phase particles on the grain growth. The simulation results show that the pinning effect is enhanced with increasing the size and the volume fraction of the second-phase particles. Abnormal grain growth may happen in certain range of the volume fraction of the second-phase particles. The final grain size reduces with the decreasing of the size of the second-phase particles when the volume fraction is fixed. A quantitative relation between the limited grain size and the parameters of the second-phase particles was obtained from phase field simulation, and the present results are consistent with experiments and Monte Carlo simulations.
