Description

The heterogeneous deformation of annealed copper subjected to one equal channel angular pressing pass was studied by scanning electron microscopy. Distinctly inhomogeneous deformation of prior annealing twins by interpenetrating slip bands was observed, and some twin-matrix interfaces displayed stair-like offsets. The intense local deformation within the annealing twins exhibits characteristics of dislocation slip and not deformation twinning
