Grain growth in a low-loss cold-rolled motor-lamination steel

This article attempts to determine the mechanisms governing the grain growth process that occurs during lamination annealing of a cold-rolled, motor-lamination (CRML) steel. A new simulation approach linking a Monte Carlo model with electron backscatter diffraction (EBSD) scans used as input has been employed to incorporate the effects of crystallographic texture on the simulated grain growth process. The results from the texture analysis and the computer simulation of the grain growth process indicate that both stored energy driven grain growth and anisotropic grain boundary growth influence the overall grain growth occurring during lamination annealing.
