Abstract: The influence of micro Na on the solidification process of Al-Si alloys was investigated by differential thermal analysis. It is found that the addition of micro Na raises the eutectic nucleation temperature and retards the eutectic crystallization of the melted Al-Si alloys, which is contrary to the traditional view point.
