The effects of initial grain size and initial grain size distribution on subsequent grain coarsening in polyphase microstructures with stable and unstable precipitates are investigated using a mean-field statistical model with an adaptive spatiotemporal mesh. The adaptive mesh enables high-throughput simulation of grain coarsening under different initial conditions. It is shown that the final grain...
Grain coarsening in the presence of second-phase particles is investigated using a mean-field statistical model. With any given initial grain size distribution and average size and volume fraction of pinning particles as input, the model predicts grain growth kinetics and temporal evolution of the grain size distribution. Simulations are performed for both stable and unstable particle populations...
