The objective of this study was to determine the effect of rolling pass on AZ31 magnesium alloy sheets, which were produced by a new concept process, so-called equal-channel angular rolling process. Processing that causes continuous shearing deformation leads to a shifting of the crystal orientation from basal plane to non-basal plane. Compared with the as-received specimens, a lower yield strength and a higher ductility of the specimens produced by equal-channel angular rolling in tensile tests at ambient temperature were presented because of the non-basal crystal orientation. Drawability was also improved greatly.
