Abstract：

In order to eliminate the microdefects easily occurred in forging process of 6061 aluminum alloy wheels, the forging process of high titanium 6061 aluminum alloy wheels was simulated by finite element software Deform3D, and the influences of deformation temperature, deformation rate and deformation amount on the microdefects in the hot forging process of wheels were studied. Then, the suitable combination of process parameters for controlling microdefects was acquired by combining the simulation results with existing forming process, which were preforging with high temperature, finalforging with low temperature, reducing preforging deformation, increasing finalforging deformation and increasing deformation rate. According to the optimum combination of process parameters, the produce test was conducted. The results show that the optimized forming process can effectively control the forging microdefects of aluminum alloy wheels.
