Grain Growth in a Low-Loss Cold-Rolled Motor-Lamination Steel

This paper attempts to determine the mechanisms governing the grain growth process that occurs during lamination annealing of a cold-rolled, motor-lamination steel. A new simulation approach linking a Monte Carlo model, with 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.
