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 623K for 1 h for the cross-roll rolled sheets. © 2011 The Japan Institute of Metals.
