摘要：

Micro-uniformity is an effective way to improve the GH4169 alloy shaft quality. The finite element model of GH4169 alloy is established by DEFORM-3D. Combined with the orthogonal experimental design method, the effect of process parameters on microscopic uniformity of cross wedge rolling of GH4169 alloy shaft was analyzed. When the temperature of the shaft is 950 degrees C, cross section reduction ratio is 40 %, the forming angle is 28 degrees, and the spreading angle is 6 degrees, the microscopic grain size distribution of the shaft member is relatively uniform. According to the optimal process parameters, the experiment of cross wedge rolling forming GH4169 alloy shaft parts was carried out. It was confirmed that the metallographic experiment and the simulation results were consistent, and the accuracy of the simulation was verified. The research method in this paper can provide theoretical guidance for determining the optimal process parameters for production.
