Abstract：

Uniaxial tension tests of AZ31B magnesium alloy sheet (0.6mm ) specimens were carried out at the temperature range between 100~350℃ and the strain rate range of 1×10-3~1×10-1s-1 on Gleeble-3500 thermal simulator. Based on the experimental results, the mechanical properties of AZ31B magnesium alloy sheet were analyzed. The results show that at low deformation temperature range of 100~150℃, strain rate has little influence on flow stress of AZ31B magnesium alloy, in contrast, the strain rate has certain effect on fracture elongation of AZ31B magnesium alloy, and high strain rate will decrease the elongation of material. At higher deformation temperature (above 200℃), strain rate has an obvious influence on flow stress, showing significant strain rate sensitivity.
