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.
