Recrystallization in the presence of inert second-phase particles has been simulated with a Monte Carlo technique. The technique is the same one as has been employed successfully to model grain growth, recrystallization and grain growth in the presence of second-phase particles. The results show that at low stored energies, the particles retard the growth of recrystallization nuclei and can prevent the recrystallization process from going to completion. At high enough stored energies, however, growth is not impeded such that the particles do not affect the kinetics of recrystallization. Post-recrystallization is strongly affected by the presence of particles because grain growth is inhibited and the microstructures to be less equiaxed than in grain growth. 15 refs., 7 figs.
