The current theory and application of Al-Si alloy mainly focus on the study of hypoeutectic and eutectic, therefore we systematically analyzed the modification process of hypereutectic Al-Si alloy based on the methods and results of predecessors. Several factors including the modification temperature, the content of modifier, the available holding time, the times of repeat melting , the casting temperature and the speed for cooling have been studied in order to understand its effects to the composition, function and performances of primary silicon and eutectic silicon.
