Simulation of recrystallization based on EBSD data using a modified Monte Carlo model that considers anisotropic effects in cold-rolled ultra-thin grain-oriented silicon steel

A Monte Carlo Potts model was developed to simulate the recrystallization process of a cold-rolled ultra-thin grain-oriented silicon steel.The orientation and image quality data from electron backscatter diffraction measurements were used as input information for simulation.Three types of nucleation mechanisms,namely,random nucleation,high-stored-energy site nucleation(HSEN),and high-angle boundary nucleation(HABN),were considered for simulation.In particular,the nucleation and growth behaviors of Goss-oriented({011}<100>)grains were investigated.Results showed that Goss grains had a nucleation advantage in HSEN and HABN.The amount of Goss grains was the highest according to HABN,and it matched the experimental measurement.However,Goss grains lacked a size advantage across all mechanisms during the recrystallization process.
