The semi-solid tensile deformation behavior of wrought AZ31 magnesium alloy
AbstractThe semi-solid tensile deformation behavior of wrought AZ31 magnesium alloy has been studied through applying a set of low strain rate (0.001s−1) hot tension tests at temperature range of 300–500°C. The results indicated a ductility drop at ∼450±25°C. This was attributed to the occurrence of eutectic reaction (L→α+γ) and the partial melting of intermetallic γ phase. The ductility was started to improve by increasing the temperature to 500°C. The latter was explained considering the effect of liquid phase on stress relaxation through accommodation of the grain boundary sliding phenomena. To further investigating the semi-solid tensile deformation behavior of the experimental alloy, the cavitations characteristics of the alloy were also examined.
