Simulation of the dynamic recrystallization of pure copper using Monte Carlo method

Along with the work hardening and dynamic recovery, the dynamic recrystallization of pure copper at 673 K is simulated with Monte Carlo (MC) method. By investigating the evolution of the plastic strain energy and the morphology of the simulated microstructure, the physical process of the system during the continuous loading procedure is studied. When the strain is small enough, nothing happens in the system. Once the strain reaches a critical value, the dynamic recrystallization occurs by the nonuniform nucleation. As the strain increase, the nucleation mechanism transforms to uniform nucleation. After some MC steps, the plastic strain energy drops from its maximum value. Ever since then, the plastic strain energy fluctuates around a fixed value.
