Abstract

Stretch formability of Mn-free AZ31 Mg alloys rolled at 618 and 723 K was investigated at room temperature. The specimen rolled at 723 K showed superior stretch formability to that of the specimen rolled at 618 K. The (0002) plane texture of the specimen rolled at 723 K exhibited a low texture intensity compared with that of the specimen rolled at 618 K. It is suggested that the modification of basal texture by the high temperature rolling contributes to activation of basal slips, resulting in an enhancement of the stretch formability. Besides, it is suggested that coarse grain size of a Mn-free AZ31 alloy seems to enhance a stretch formability, because twins become easily generated during tensile loading.
