Effect of surface integrity induced by shot peening on high-temperature fatigue property of K4169 alloy

Effect of surface integrity induced by shot peening on high-temperature fatigue property of K4169 alloy

The surface roughness, residual stress and micro-hardness of K4169 alloy specimens were characterized by roughness tester, X-ray diffraction（XRD）stress tester and micro-hardness tester. The results indicate that median fatigue lives of the specimens increased by 10.2-43.9 times after SP treatments c...
