Description

Highlights: • Superplasticity of AZ31 alloy containing 0.5 wt % Ca was studied. • AZ31-0.5Ca alloy showed an improved superplasticity as compared to Ca-free alloy. • The improved performance was attributed to structure stability induced by 2nd phase particles. In this short communication, the superplasticity of AZ31-0.5Ca Mg alloy was investigated and was compared to that of the Ca-free counterpart (AZ31 Mg alloy). For this purpose, AZ31 and AZ31-0.5Ca Mg alloy samples were subjected to elevated temperature tensile tests at various strain rates. The results reported in this work showed that the Ca addition lead to a higher superplasticity (~320%) at strain rate and temperature of 0.001 s−1 and 300 °C, respectively, as compared to that observed in the Ca-free AZ31 alloy.
