铸锻一体化工艺具有广阔的应用前景，特别是对于形状复杂、性能要求高的产品。利用Thercast和Forge软件对A356合金汽车控制臂的ICFP进行了数值模拟。结果表明，在浇注温度为0.680 °C、模具温度为150°C、锻造启动时间为1s、锻造行程为2mm的条件下，可获得无气孔的零件。利用ICFP平台制作了缩尺汽车控制臂。实验结果证实了数值模拟的准确性。与压铸相比，ICFP获得了更好的力学性能，其抗拉强度为238.96MPa，伸长率为8.13%，这是由于ICFP组织细小，无气孔。本研究通过仿真解决了工艺参数的设计和优化问题，对促进ICFP的应用起到了重要作用。
Integrated casting and forging process (ICFP) has broad application prospects, especially for products with complex shapes .and high performance. Numerical simulation of the ICFP of A356 alloy automobile control arm was carried out on Thercast and Forge software. The numerical results showed that part without porosities was obtained at pouring temperature of .680°C, mold temperature of 150°C, forging start-up time of 1s, and forging stroke of 2mm. The scaled automobile control .arms were fabricated by ICFP platform. The experimental results confrmed the accuracy of the numerical simulation. Better .mechanical properties involving tensile strength of 238.96 Mpa and elongation of 8.13% were obtained by ICFP than diecasting due to the fne microstructure without porosities. This research has resulted in a solution of the design and optimize .of process parameters through simulation, which played an important role in promoting the applications of ICFP.
