Abstract

Shearing deformation was applied to AZ31 magnesium alloy sheets by a new concept processing, so-called equal channel angular rolling (ECAR) processing for the development of a different crystal orientation compared with the as-received sheets. The results indicated that deformation behavior was changed obviously and a clear yield phenomenon appeared followed by a clear work hardening state region after ECAR processing. And the elongation-to-failure of the ECARed specimens exhibited over 24%, which was almost twice larger than that of the as-received specimens. All of these can be owing to the modification of the crystal orientation.
