Abstract

A coarse-grained Cu-16 wt.% Ag alloy was processed by equal channel angular pressing (ECAP) for one pass to reveal the shear deformation behaviors by scanning electron microscope and electron backscattering diffraction. The evolution of shear bands was found to be affected by both the parallel and vertical shearing to the intersection plane (IP) of the ECAP die, indicating that, besides the shearing along IP, the shearing vertical to it also plays an important role during the plastic deformation.
