Direct observations of microstructural evolution in a two-phase Cu–Ag alloy processed by high-pressure torsion
Direct observations of microstructural evolution in a two-phase Cu–Ag alloy processed by high-pressure torsion
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 the center of the disk also experiences a strain after five revolutions.

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 the center of the disk also experiences a strain after five revolutions.
