Popis:	A Monte Carlo model is modified by using Turnbull–Fisher's nucleation rate model to simulate the ultra-fine microstructure evolution during annealing of AZ31 processed by equal channel angular pressing (ECAP). The simulation is utilized to predict the grain size of AZ31 samples at different annealing temperatures and pass numbers of ECAP. Also, in the simulation the constant nucleation rate model is assumed and a good agreement is achieved between the simulation results and experimental data. Therefore, it can be concluded that the constant nucleation rate is prevailed during the microstructure evolution.
