Abstract

Mg-20Zn-8Al-xCe(x = 0-2 wt.%) alloys were prepared by metal mould casting method, the effects of Ce on the microstructure and mechanical properties of the alloys were investigated. The results showed that the dendrite as well as grain size were refined by the addition of Ce, and the best refinement was obtained in 1.39% Ce containing alloy. The main phases in the as-cast alloys were α-Mg and τ-Mg₃₂(Al, Zn)₄₉, and Al₄Ce phase was found in the alloys contained more than 1.39% Ce. The addition of Ce improved the mechanical properties of the alloys. The strengthening mechanism was attributed to grain refinement and compound reinforced.
