摘要

The objective of this study was to investigate the cross-roll rolling process effects on microstructures and mechanical properties of AZ31 Mg sheet about rolling angle, in which the roll axes were tilted 0°, 2.5°, 5° and 7.5° away from the transverse direction. Three-dimensional FEM simulation proved that increasing the cross-roll angle, the through-thickness variation of effective strains decreases extremely. The cross-roll rolled and subsequently annealed samples have the uniform and fine grain size at whole thickness layers with increasing the cross-roll angle from 0° to 7.5°. The result of tensile test discloses that while the increase in cross-roll angle can scarcely affect on the strength of samples, it can improve the formability of samples remarkably.
