The results indicate that adding Al-10Sr or Mg-10Sr master alloys to AZ31 magnesium alloy could effectively reduce its grain size, but the refinement efficiency of Mg-10Sr master alloys is higher than that of the Al-10Sr master alloys. In addition, for a given melt holding time, the refinement efficiency of the two master alloys respectively increase with Sr adding amount increasing from 0 to 0.1wt%, and the increasing laws are similar. For a given Sr adding amount, the refinement efficiency of Al-10Sr mater alloy gradually increases with the melt holding time increasing from 20 to 80min, but its changing is not obvious for the Mg-10Sr mater alloy. The difference of refinement efficiency for the Al-10Sr and Mg-10Sr master alloys might be related to the dissolution modes and rates of Al4Sr and Mg17Sr2 phases in the melt of AZ31 magnesium alloy.
