WebFeb 25, 2000 · We find evidence of obvious creep near room temperature with threshold stress σ 0 that decreases with increasing temperature. The steady state creep rate at 0.23 T m was measured to be as large as 1 × 10 −6 s −1 , which is much larger than that for coarse-grained Cu and the consolidated nc Cu (8 × 10 −9 s −1 ) ( 10 ) as well.
