针对铝基碳化硅压力浸渍过程中铝液的流动性问题，采用ANSYS软件对铝合金熔液的注入和冷却过程进行了分析，计算表明将400 g铝合金熔液注入模腔中，铝液在注入后6．8 s内处于流动性较好的状态，随后流动性逐渐减弱。设计相同尺寸工装进行压力浸渍试验，结果表明铝液在注入6．8s内呈现比较好的流动状态，与计算结果相符；此时采用活塞加压实现了碳化硅基材的浸渍，获得了性能良好的铝基碳化硅复合材料。

Aiming at the problem of melt flow in the process of pressure infiltration for the preparation of AlSiC composite materials , it simulates the pouring and cooling process of aluminum alloy melt based on APDL program of ANSYS software.The numerical results show that the melt flow performance is excellent within 6.8seconds af-ter 400 g aluminum alloy poured to mould cavity , and then the flow performance become weak with time subse-quently .It designs the same size tooling for pressure infiltration experiment .The experiment results show that the melt flow performance is excellent with 7 seconds after aluminum alloy melt poured to mould cavity , the numerical experimental results agree with each other .It obtains AlSiC composite materials with excellent performance from the piston pressure infiltration of SiC base .
