Microstructures and Texture Development of the Cross-Roll Rolled AZ31 Alloy Sheet at High Temperature

Abstract

The texture development and microstructural evolution have been investigated for the AZ31 alloys rolled by cross-roll rolling at 823 K. After the AZ31 magnesium sheets were rolled by cross-roll rolling at 823 K, the total reduction in thickness of 65% were achieved after two pass rolling. The resultant microstructures are homogeneous and refined for the surface and center layers. The (0002) basal texture is significantly weakened after annealing at 623 K for 1 h for the cross-roll rolled sheets.
