Abstract

Numerical simulation of thixoforming for high fraction semi-solid magnesium alloy has been conducted to analyze the stress

strain distribution and temperature field during thixoforming process

and forming characteristics between semi-solid billets and conventional billets has been compared.The results indicate that semi-solid magnesium alloy exhibits low deformation resistance and uniform stress and strain distribution

which provides a reference to optimizing thixoforming parameters for semi-solid magnesium alloy.
