Paper Title:
Microstructure and Texture Evolution during Equal Channel Angular Extrusion of Pure Copper: Effect of Strain Rat
  Abstract

Effect of strain velocity on the refinement of severe plastic deformation structure of ECA pressed pure copper was studied using transmission electron microscope(TEM) and electron back-scattered diffraction (EBSD) analysis. Formation mechanism of unltra-fine grain with high angle boundary was discussed. It was found that exceedingly fast stain rate can significantly increase the fraction of high angle boundary, up to 76%, and make grain refine further, up to 0.23μm.
