铸锻一体化工艺是一种结合铸造和锻造优点的新型制造方法。该工艺可生产形状复杂、力学性能优良的铝合金汽车轮毂等铝结构件。利用Forge软件模拟了不同工艺参数对汽车轮毂ICFP的影响。通过实验研究了锻造区和非锻造区组织。结果表明，模具温度、注射活塞静压、锻造速度和物料流量对成形过程有显著影响。与非锻造区相比，锻造区组织更细、更均匀、更致密。同时可以消除铸件缺陷，提高铸件的力学性能。
Integrated casting and forging process (ICFP) is a new manufacturing method combining the advantages of both casting and forging. Aluminum structure parts, such as aluminum alloy automobile wheel, with complex shape and excellent mechanical properties can be produced by this process. The effects of different process parameters on the ICFP of the automobile wheel were simulated by Forge software. Microstructure of forging region and the nonforging region were studied by experiment. The results show that die temperature, static pressure of the injection piston, forging speed, and material flow have significant influences on the process. Compared with nonforging region, the microstructure of forging region becomes finer, more uniform, and denser. Meanwhile, the casting defects can be removed and mechanical properties improved.
