Abstract: Based on the mechanism of grain growth during desorption-recombination process of NdFeB alloy, Monte Carlo (MC) physical model was introduced to simulate microstructure evolution during grain growth process of Nd2Fe14B phase at various processing temperatures. Furthermore, the grain growth kinetics was studied. The analysis shows that the grain growth can be well simulated, and the average growth exponent n≈0.8 for the entire time domain by fitting the experimental data with the theoretical model, higher than the normal value of 0.5.
