A Study of Shot Peened Spring Steel(SUP9) for Fatigue Life Improvement and Compressive Residual Stress Disappearance on the High Temperature

Abstract
The compressive residual stress, which is induced by shot peening process, seems to be an Important factor in increasing the fatigue strength. And then it was showed that residual stress was disappearenced at the high temperature. The fatigue charateristic investigation of a SUP9 spring steel processed shot peening is performed by considering the high temperature service conditions in the range of room temperature through
