Stress–strain curves of nanocrystalline Ni are compared to reported creep rate–strain curves at 298 and 373K. Both show a limited range of strong work hardening followed by a steady-state. The stress dependence of the steady-state creep rate explains the continuous decrease in creep rate found in tests at constant load. The stress exponent of strain rate, n, decreases markedly with decreasing stress,...
