中文摘要	with the aim to further improve the mechanical properties of mg-al-re-based alloy, mg-3.0al-1.8ce-0.3y-0.2mn alloy was prepared by high-pressure die-casting technique. the microstructure, thermal stability of intermetallic phases and mechanical properties were investigated. the results show that the alloy is composed of fine primary alpha-mg dendrites and eutectic in the interdendritic regions. the intermetallic phases in eutectic are al-11(ce,y)(3) and al-2(ce,y) with the former being the dominant one. the thermal stability of al-11(ce,y)(3) is conditioned. it is basically stable at temperature up to 200 degrees c within 800 h, while most of the al-11(ce,y)(3) intermetallics transform to al-2(ce,y) at higher temperature of 450 degrees c for 800 h. the alloy exhibits remarkably improved strength both at room temperature and 200 degrees c, which is mainly attributed to the reinforcement of dendrite boundaries with al-11(ce,y)(3) intermetallics, small dendritic arm spacing effect as well as the solid solution strengthening with y element.
