摘　　要：采用仿真软件ABAQUS对Cu-38Zn合金的交叉模压过程进行仿真,并对Cu-38Zn合金在等效应变过程中显微组织及力学性能的变化进行了研究。结果表明,Cu-38Zn合金经不同交叉模压形变后沿长度方向的等效应变和显微硬度分布不均匀。5周期交叉模压形变后晶粒尺寸变小,分布着大量的孪晶组织。并且,试样心部的显微硬度比其表面硬度低约26%。The cross mould pressing process of the alloy Cu-38 Zn was simulated using the simulation software ABAQUS,and the microstructures and mechanical properties changes of the alloy Cu-38 Zn during equivalent strain process were investigated. The results show that the distributions of the equivalent strain and micro hardness of the alloy Cu-38 Zn along the length direction are not uniform after different cross mould pressing. The grain size of the alloy becomes small after5-cycled cross mould pressing, and a large amount of twins distributes in the matrix. Furthermore, the micro hardness of the sample at the core is about 26% lower than that at the surface.
