Microstructure and mechanical properties of Mg-8Al-xNd alloy with different Nd content prepared by EVO.53D cold chamber press at room and elevated temperature were investigated by an optical microscope and tensile testing.The results indicate that the microstructure of die cast Mg-8Al alloy with the precipitation phase can be refined with Nd addition.The highest tensile strength and yield strength can be examined with 0.5% Nd content.Tensile strength and elongation of the die cast Mg-8Al alloys can be increased by more than 10% and by more than 43%

respectively

with adding Nd after tensile testing at 150 ℃.
