In this paper, superplastic tensile testing and gas bulging forming of AZ31 and AZ31 + Y + Sr magnesium alloys produced by twin roll casting (TRC) and sequential hot rolling were carried out. At 673 K, the superplastic formability of the TRC AZ31 magnesium alloy sheets added Y and Sr elements has improved significantly compared to the common TRC AZ31 sheets. Formations of cavities on the bulging part go through three stages of the nucleation, growth and aggregation, finally cavities merging lead to rupture at the top of the bulging part.

In this paper, effects of texture on tensile property of extruded AZ31 magnesium alloy are investigated by acoustic emission (AE). The results show that the extruded AZ31 magnesium alloy used in this research has the strong texture of and tensile anisotropy. The yield strength of TD-sample is about 80MPa, which is half of that of ED-sample. AE results show that the AE count of the TD-sample is higher than that of the ED-sample. These AE results suggest that there are more deformation twins in the TD-sample than in the ED-sample. It can be concluded that the deformation twinning can strongly influence the anisotropy, which is mainly due to the flow stress relief induced by twinning and the interaction of twins and dislocations during the strain hardening.
