摘要	The measured hardness of nanocrystalline Cu with grain sizes (( as small as 10 nm still follows the Hall-Petch relation. A rate sensitivity of 0.06 +/- 0.01 and a flow stress activation volume of 8b(3) were determined at d = 10 nm, suggesting grain boundary activities are enhanced but not yet dominant in the plastic deformation.
