摘要：

The influence of added elements on the solidification process of Al-Si alloys was systematially investigated by DTA and thermal analysis. It was obtained that Na Sr in the melt can raise the temperature of eutectic solidification. Our work indicates that the traditional retard nucleation theory of modification may have some shortcomings.
