Heterogeneous nucleation is a critical factor for grain refinement magnesium alloys. The paper reports the Al-9wt.%Mg-10wt.%SiCp master alloy were prepared by adding SiCp into the Al-Mg molten with stirring in 610-595℃, which were introduced into AZ91. Experimental results indicated Al4C3 were in situ synthesis on the surface of SiCp by the reaction between SiCp and Al in 850℃, which could be as nucleant substrate for primary Mg during the solildification of magnesium alloys. This investigation provided a novel idea for grain refinement Mg-Al alloy.
