Effects of Texture on Tensile Property of Extruded AZ31 Magnesium Alloy Investigated by Acoustic Emission

摘要：

　　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 1120<1010> 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.
