| Abstract | Disks of a coarse-grained Cu-28 wt.% Ag alloy were processed by high-pressure torsion, and the decorative eutectic regions were used to reveal the evolution of deformation. It is shown that the deformation starts at the peripheries of the disks in the form of local vortices and then spreads inwards with increasing the number of revolutions. The experimental evidence confirms that die center of the disk also experiences a strain after five revolutions. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved |
