been used to improve the effects of heterogenous nucleation of near eutectic and hypereutectic Al-Si alloys [15]. Previous research [16] reported that Cu-P master alloy can refine the primary Si in hypereutectic Al-Si alloys. Additionally, Al-3P and Al-10Sr master alloys can refine primary Si and eutectic Si in Al-30Si alloys [17]. WANG et al [18] reported that the sub-rapidly solidified Al-10Ti......
