%X The Al-8.62% Sr master alloys with same composition but differentmicrostructures have different modification efficiency for Al-Si alloy. When Al-Sr ingot,corresponding to 0.1 %Sr in Al-Si alloy, or rapidly solidified Al-Sr sheet, coressponding to0.05%Sr in Al-Si alloy, was added, the modification rating of the eutectic Al-11 .8% Si alloyreaches class 5 at the condition of sand mold casting. At the permanent mold condition, bythe addition of Al-Sr ingot, corresponding to 0.06%Sr in Al-Si alloy, or rapidly solidifiedAl-Sr sheet, corresponding to 0.03%Sr in Al-Si alloy, the modification rating of the Al-Si alloy reaches class 6. It has been shown that the difference of the modification rating is attributed to the structural heredity effect.
