摘 要：<正> To obtain the finer primary silicon crystals, the proprietary Al-P master alloy was adopted to modify the eutectic Al-Si alloys and the most suitable modification process was made in the experiments. The SEM （Scanning Electron Microscope） and DSC （Differential Scanning Calorimeter） analysis indicate that the Al-P modifier has more advantages over Cu-P and Fe-P modifier in easily addition, no elemental alteration and less undercooling of primary silicon’s solidification, which suggests the Al-P master alloy is an effective modifier of eutectic Al-Si alloys.
