Strain-Rate Sensitivities of Different Deformation Mechanisms in AZ31B Magnesium Alloy Sheet at Various Temperatures

The evolutions of strain-rate sensitivity (SRS) in two slip modes, basal null null and prismatic null null in AZ31B alloy sheet, were studied at different temperatures with both experiments and simulations. With increasing deformation temperature, the AZ31B alloy sheet becomes more sensitive to strain rate under rolling direction tension. Meanwhile, the anisotropy (r-value) also presents a clearly increasing trend with loading rate at...
