Abstract

Deep drawing of magnesium alloy sheet is conducted at elevated temperatures($200{\sim}300^{\circ}C$) to improve the press formability because of low formability at room temperature. Then magnesium alloy sheet formability is known to be very sensitive to the strain rate. In this paper, we conducted warm deep drawing tests of magnesium alloy AZ31 sheet for various punch velocities. We examined the forming velocity effect on the deep drawing formability and the correlation with the tensile test result.
