摘要：
The effect of 12 elements, Li, Na, K, Mg, Ca, Sr, Ba, La, Sm, Y, Sb and Bi, on the modification of Al-Si eutectic alloys was systematically investigated by means of microstructural observations. The range of modifying concentrations for each modifier under various cooling rates was determined and the effect on the microstructure of Al-Si eutectic alloys with the same modifier concentration but varied cooling rates was also studied.
