Abstract
The continuous cyclic bending (CCB) and subsequent annealing made it possible to produce the gradient microstructure with the coarse-grained surface and the fine-grained central layers in an Al-Mg-Mn alloy sheet. The microstructural evolution during annealing in the continuous cyclic bent (CCBent) sheet was simulated by Monte Carlo (MC) simulation of recrystallization in order to investigate an effect of working and annealing conditions on thickness fraction of coarse-grained layer in this study. Further, we attempted to reproduce the thickness fraction of coarse-grained layers that reported by the experiment in the Al-Mg-Mn alloy sheets by the MC simulation.
