Abstract

A phase field model which contains two phase grain growth in binary alloys was used to study the effect of the same or different initial grain fraction and the different diffusion coefficients on the two-phase grain structure evolution. The results show that the low volume fraction of grain, coarsening power is only controlled by the Ostwald coarsening and through distance interval of grain. The coarsening of the second phase particles in the dominant phase is affected by the number of grain boundaries, grain boundaries will be pinned by the grain, which is affected by the area fraction of the grain. When the diffusion coefficient is large, the diffusion rate is fast, and the grain boundary mobility rate is large.
