中文摘要	Disks of a coarse-grained Cu-28 wt.% Ag alloy and pure Cu were processed by high-pressure torsion and the microhardness was investigated as a function of the imposed strain. It is shown that the Cu Ag alloy displays a much stronger strain hardening capability than Cu due to a continuous refinement of the microstructure. A two-stage Hall-Petch relationship was obtained for the Cu-Ag alloy which is attributed to the development of multi-strengthening mechanisms. (C) 2011 Acta Materialia Inc. Published by Elsevier Ltd.
