Effect of Surface Integrity of Turned GH4169 Superalloy on Fatigue Performance

Effect of Surface Integrity of Turned GH4169 Superalloy on Fatigue Performance

Through turning and rotary bending fatigue test, the effect of turning feed on GH4169 superalloy surface integrity, and the effect of surface integrity on fatigue life were studied. The results show that the surface roughness <i>R</i><sub>a</sub> decreases from 1.497 μm to 0....
