Abstract
The forming process of rheocasting for ZL201 alloy, microstructure and mechanical properties of the formed parts were simulated by the AnyCasting software, and the simulated results were compared with those of the actual casting. The optimal process parameters of rheocasting were obtained, i.e. pouring temperature of 600℃, die temperature of 240℃, low injection velocity of 0.1 m/s, velocity switching time of 1.5 s, and high injection velocity of 1 m/s. Using the parameters above, the part was filled up stably without gas porosity, and had the grain size of 72.56 μm, the hardness of 70.8 HV, and the average tensile strength of 212.5 MPa.关键词
