Abstract
Mechanical properties of AZ31 H24 magnesium alloy sheets were investigated by tensile tests over a wide temperature range from room temperature to 400°C at 1.3 × 10-3 s-1. The deformation behaviour of the AZ31 alloy sheet was also investigated after annealing. The yield stress and the maximum stress decrease with increasing temperature. The values of the yield stress and maximum stress of the samples with tensile axis parallel to the rolling direction are lower than those of the samples deformed perpendicular to the rolling direction. The elongation to failure increases very rapidly with increasing temperature. The results are explained by the dislocation glide in the basal and non-basal slip systems and by deformation twinning.

Key words
