Thermal Relaxation of Shot Peen Induced Residual Stresses in a Nickel-Base Superalloy

reportActive / Technical Report | Accesssion Number: AD1175634 | Open PDF

Abstract:

Shot peening induces compressive residual stresses in components that positively influence fatigue life. Thermal and mechanical loading causes those residual stresses to relax. The hole drilling method and xray diffraction is used to measure the thermal relaxation of residual stresses in the nickel-base superalloy ME3.
