结合压铸和锻造的优点，设计了一套新型成形模具，首次提出了双控制成形思想。以AM60B合金摩托车轮毂为典型零件，验证了双控制成形的优点。研究了压力对双控制成形零件力学性能和组织的影响。结果表明，双控制成形成形的零件具有较高的力学性能和复杂的形状。与压铸件相比，成形件的力学性能显著提高，组织由粗枝晶变为细等轴晶。随着压力的增大，成形件中的缩孔和微裂纹明显减少甚至完全消除。当压力为4000 kN时，合金的抗拉强度达到265.6 MPa，伸长率达到21%，且由于高压引起的过冷度较大，合金的组织呈现出细小均匀的等轴晶。
A set of novel forming die combining the advantages of dies casting and forging was designed, by which double control forming idea was firstly proposed. The motorcycle wheel made of AM60B alloy was used as the typical component to demonstrate advantages of the double control forming. The effect of pressure on the mechanical properties and microstructure of the parts formed by double control forming was investigated. The results showed that high mechanical properties and complex shape were achieved in the parts formed by double control forming. Compared to die casting, the mechanical properties of the formed part significantly increased and the microstructure changed from the coarse dendrites to fine equiaxed grains. The shrinkage voids and microcracks in the formed parts were obviously reduced or even completely eliminated with the increase of pressure. When a pressure of 4000 kN was applied, the optimal mechanical properties such as ultimate tensile strength of 265.6 MPa and elongation of 21% were achieved and the microstructure was characterized by fine and uniform equiaxed grains due to the large undercooling degree caused by the high pressure.
