by phase field model. The simulation results indicate that morphological evolutions are controlled by a transformation-induced elastic strain during a solid state precipitation and various types.... Moreover, the stress-induced reverse coarsening phenomenon, which depends on the lattice misfit and volume fraction of precipitates, is found for medium lattice misfit in the stage of coarsening. Key......
