Abstract In this work, hypereutectic Al-Si melt was treated by melt quenching device. The effects of Si content and smelting process on the solidification microstructure of hypereutectic Al-Si alloys were investigated by means of optical microscope, scanning electron microscope and X-ray diffractometer. The results show that when hypereutectic Al-Si alloy was melted at 800 ℃ for 30 min, melt supercooling could inhibit the precipitation of primary Si during the solidification process of Al-(14—18)Si alloy. When Al-18Si alloy was melted at 800 ℃ for more than 30 min, the precipitation of primary Si could be completely inhibited if the melt supercooled Al-18Si alloy was solidified in room temperature metal mold and the solidification microstructure without primary Si could be obtained.

Key words： hypereutectic Al-Si alloy melt supercooling primary Si solidification microstructure
