摘要：

The effects of shot peening and shot peening combined vibration finishing on the fatigue properties of GH4169 superalloy were studied contrastively. The surface morphology, surface structure, roughness, microhardness and residual stress field of the sample were analyzed by scanning electron microscope, roughness profiler, microhardness tester, and X- ray stress tester, and the internal relationship and mechanism of surface integrity and fatigue performance were discussed. The results show that the composite treatment is better than single shot peening treatment in improving the fatigue performance of GH4169 superalloy. The composite treatment increases the room temperature fatigue strength of GH4169 superalloy by 21.6%. Preheating at 500 degrees C for 100 h reduces the fatigue strength of composite strengthened GH4169 superalloy by 6%, but it is still 14.29% higher than that of the base material. That is to say, the composite treatment can effectively improve the fatigue resistance of GH4169 superalloy under working conditions from room temperature to 500 degrees C.
