摘要：

Mg-6Al-1Zn magnesium alloy sheets were rolled at high temperatures of 723-793 K using differential speed rolling. The Erichsen value remarkably increases about 1.5 times due to the weakened basal texture regardless of the coarser grains with increasing the rolling temperature from 723 to 793 K. The sheet rolled at 793 K exhibits a combination of a superior stretch formability with an Erichsen value of 7.0 and a high tensile strength of 300 MPa at room temperature.
