Abstract：
The effects of modification and sub-rapid solidification on the microstructure of Al-7Si alloy were studied by changing the cooling rate and the content of the modifier. The results show that the microstructure of Al-7Si alloy is refined under sub-rapid solidification. Under the condition of sub-rapid solidification, the best modification effect was 0.02%Sr.
