中文摘要	mg-4al-xce-0.3mn (x=0, 1, 2, 4 and 6 wt.%) alloys were prepared by high-pressure die-casting. the microstructures, mechanical properties and corrosion behavior were investigated. the cross-section of test bar is divided into the fine skin region and the relatively coarse interior region by a narrow band. the dendritic arm spacing is greatly reduced and the secondary phases al(11)ce(3) and (al, mg)(2)ce with the former being the dominant one substitute the mg(17)al(12) phase with addition of ce. when ce content reaches 4 wt.%, the alloy exhibits an optimal cost performance ratio. the improved mechanical properties maintained up to 200 degrees c are mainly related to the fine grain size and the main strengthening phase al(11)ce(3), which is present in a high volume fraction, and possesses fine acicular morphology and relatively good thermal stability. the improved corrosion resistance is attributed to the microstructure modification of the alloys and the corrosion product films.
