Response to comments on “Influences of crystallographic orientations on deformation mechanism and grain refinement of Al single crystals subjected to one-pass equal-channel angular pressing”

Abstract

We further discuss the deformation mode to clarify the possible shear mechanism during equal-channel angular pressing (ECAP). A repeated ECAP test for crystal II was carried out and its crystallographic orientation, rigid body rotation and misorientation scatter are consistent with reports elsewhere. We believe that except for along the intersection plane (IP), shear deformation along the normal plane to the IP can also activate the preferential slip system of single crystals during ECAP, at least on the microscale.
