中文摘要	mg-4al-0.4mn-xpr (x = 1, 2, 4 and 6 wt.%) magnesium alloys were prepared successfully by the high-pressure die-casting technique. the microstructures, mechanical properties, corrosion behavior as well as strengthening mechanism were investigated. the die-cast alloys were mainly composed of small equiaxed dendrites and the matrix. the fine rigid skin region was related to the high cooling rate and the aggregation of alloying elements, such as pr. with the pr content increasing, the alpha-mg grain sizes were reduced gradually and the amounts of the al2pr phase and all, pr-3 phase which mainly concentrated along the grain boundaries were increased and the relative volume ratio of above two phases was changed. considering the performance-price ratio, the pr content added around 4 wt.% was suitable to obtain the optimal mechanical properties which can keep well until 200 degrees c as well as good corrosion resistance. the outstanding mechanical properties were mainly attributed to the rigid casting surface layer, grain refinement, grain boundary strengthening obtained by an amount of precipitates as well as solid solution strengthening.
