AbstractIn order to study the phase transformations in consideration of the grain boundary diffusion, the diffusion along grain boundary was incorporated in the quantitative phase field model coupled with the Kim-Kim-Suzuki (KKS). The effect of the number of grain boundaries, the spatial distribution and size distribution (PSD) of alpha phase on the alpha phase dissolution was researched. The results show that grain boundaries are a faster element diffusive path. The larger the number of grain boundaries is, the faster the kinetics of alpha phase dissolution is. Namely, the kinetics of alpha phase dissolution is fastest when the phase is located at triple junctions. However, the dissolution kinetics is of little difference when alpha phase is on the grain boundary and distributed uniformly in the matrix. Compared to the phase dissolution rate in two-dimensional condition, the effect of the grain boundary diffusion on dissolution kinetics is more obvious in three-dimensional condition. When phase transformation is dominated by bulk diffusion of solute, the spatial distribution of alpha phase is a main factor affecting the alpha phase dissolution. But when phase transformation is dominated by grain boundary diffusion of solute, the effects of other size distributions on the dissolution of alpha phase are not obvious except for uniform PSD.
