抄録

Mechanical properties and press formability at room temperature of AZ31 Mg alloy processed by single roller drive rolling were compared with those of the one processed by normal rolling. The single roller drive rolled specimens showed the weaker intensity of (0002) texture. As a result of tensile tests, there was no difference in unidirectional elongation between them. However, results of conical cup tests show that the press formability of the single roller drive rolled specimen was rather better. The planar anisotropy was lower and twins were observed for the single roller drive rolled specimen, indicating that the weaker intensity of texture leads to twining, resulting in the lower planar anisotropy.
