摘要

The initial solidified phase, such as coarse α phase and scattered chill structure, affects the flow length of the aluminum die casting alloy. The effects of initial solidified phase on the flow length of ADC12, ADC10 and AC2A were investigatedusing a cold chamber type die casting machine. The flow length decreased with the area ratio of the initial solidified phase. The structure of the initial solidified phase also affects on the flow length. The deviation of flow length increased with thecontent of Si. The critical solid fraction of fluid flow was also estimated using the relationship between the initial solidified phase and flow length. The critical solid fraction of fluid flow was about 0.6.
