Abstract

Creep tests on shot-peened nickel-base superalloy specimens, subject to applied stresses near and above monotonic yield, have been performed to characterize residual stress relaxation under sustained loading at 650 °C in IN100. Retained residual stress–depth profiles, measured on crept samples, show that yielding during initial loading produces the largest change in the residual stress profile. Furthermore, it is shown that applied stresses below yield exhibit similar retained residual stress profiles in the axial and transverse orientations.
