A parametric study of dynamic recrystallization was undertaken using the Monte Carlo method. Cells in the simulation domain were connected to six neighboring cells across interfaces whose energy varied from 0 to 5 depending on the difference in orientation between the cells. The internal energy of cells was increased during each Monte Carlo step (MCS). A cell was allowed to grow (take up the orientation of one of its neighbors), recrystallize (take up a new orientation), or remain unchanged. Three different energy input rates were used in the simulations. Results presented include the effect of energy input rate on the internal energy, boundary energy, nucleation and growth events, and the structural evolution of the domain. Some comparisons are made with phenomenon observed during dynamic recrystallization of metals.
