AbstractBreaks in the stress/rupture time and stress/creep rate relation are known to occur during high-temperature creep. In the present work these deflections are explained in terms of different stress-dependences of the intracrystalline deformation rate and the rate of grain-boundary sliding. The transition from trans- to intercrystalline fracture, which coincides, at least approximately, with these breaks, is suggested to be due to the increased grain-boundary sliding at stresses below the break.
