Currently, castings and die-castings with ductility are needed. For this reason, modification treatment is necessary. However, no theory of modification mechanism has been established to date. Therefore, in the present study, Al-7%Si molten alloy added with Sr was water quenched as the starting point for developing the technique for improving the Si phase of the eutectic crystal. Furthermore, we summarized information on conventional representative theory and recent knowledge about the growth mechanism of the eutectic crystal.
