Constitutive analysis of wrought magnesium alloy Mg–Al4–Zn1

Stress–strain data were collected from uniaxial compression tests over a wide range of strain rates and then corrected for deformation heating. The effect of the data correction on the constitutive behaviour, incorporating a strain-dependent parameter, of wrought magnesium alloy Mg–Al4–Zn1 was evaluated. The results show that the strain-dependent analysis provides a constitutive equation that leads to a good agreement between the calculated and measured flow stresses in the relevant temperature range.
