Abstract

Three types of AZ31 alloy samples, numbered with A, B, C, with various texture and microstructure condition were hot-rolled in single pass to investigate the different mechanism of shearing bands formation. Shearing bands came into being via twinning related grain fragmentation and DRX in Sample A while via rotational recrystallization in Sample B. Twinning played the most important role in shearing bands formation in Sample C. DRX and twinning are the two major elements in the formation of shearing band in magnesium alloys. Contrastive study indicated that sharper texture would increase the influence of twining while small size would promote the recrystallization in shearing bands formation.
