Abstract

We further discuss the deformation mode to clarify the possible shear mechanism during equal-channel angular pressing (ECAP). Based on the specially designed experiment, it is suggested that except for along the intersection plane (IP), shear deformation along the normal of the IP can also activate the preferential slip system of single crystals during ECAP, at least on the micro-scale, indicating a strong effect of crystallographic orientation on the microstructural evolution and refining mechanism of crystalline materials.
