摘要

Solidification process of A357 alloy with Sr addition was investigated in this paper. In particular, the effects of strontium and cooling rate on α-Al dendrite and Al-Si eutectic characteristic temperature were characterized by differential thermal analysis (DTA). Sr addition not only modifies the Al-Si eutectic, but also affects the morphology and structure of primary α-Al dendrite. Sr decreases the growth temperature of α-Al dendrite and Al-Si eutectic, and it also affects the dendrite growth mechanism. It has been found that such effect becomes more significant with higher cooling rate,.
