Evaluation of Variation Mechanical Properties in AZ91D Magnesium Alloy Processed by Extrusion and ECAP

Abstract:

Microstructure evolution and mechanical properties of AZ91D magnesium alloys which was processed by EX-ECAP at 473K were investigated in this study. Microstructural inspection showed that the EX-ECAP was effective in refine grain size of the alloy. Tensile testing at room temperature showed that the ductility, strength and hardness of the alloy have been significantly increased by EX-ECAP. The alloy exhibited excellent superplastic properties in the form of the maximum elongation of ~218% at 473K using an initial strain rate of 3×10^-4s^-1.
