Creep rates in fine-grained Nb were measured at 600 Β°C using free-standing Cu/Nb polycrystalline multilayered foils. For specimens with layer thicknesses ranging from 0.5 to 5 lm and Nb grain sizes ranging from 0.43 Β± 0.05 to 1.87 Β± 0.13 lm, two distinct regimes were observed. At high stresses, the
