Abstract

High temperature anelastic relaxation measurements have been made on Ni-20 wt% Cr alloys containing 0 to 180 at.ppm Ce. Anelastic relaxation mechanisms for grain boundary sliding are presented and observed high temperature relaxation peaks are discussed. A large hysteresis in the high temperature background between heating and cooling cycles is observed, which is attributed to a grain boundary phase transformation.
