Abstract：The modification effects of Na modifier (0.1%, 1.5%, 2.5% and 3%) on eutectic Al-Si alloys were investigated by rapid detection of computer systems. The results showed that there is a quantitative relationship between the modification under-cooling (△T) and the modification effect. When △T≥5 ℃(Na is 2.5%), the modification effect is good, and the modification effect is optimal when △T=8 ℃(Na is 3%). The criterion is in good accordance with mechanical properties, fracture morphology and microstructure.
