Establishing a fatigue life prediction model considering the machined surface state is of great significance to improve fatigue life prediction accuracy. Fatigue tests with different machined surface states of GH4169 alloy were conducted firstly. The influence of surface state parameters on the fatigue life was analyzed. Then, the machined surface stress concentration factor and residual stress were introduced into the fatigue crack initiation and propagation models. Finally, the fatigue life prediction model of GH4169 material considering the surface states was established. The prediction results based on the proposed model are almost within a factor of two scatter band of the test results.
