Abstract

The current research of ultra-fine grained metallic materials processed by severe plastic deformation（SPD）was described

focusing on equal channel angular pressing（ECAP）and high pressure torsion（HPT）.The grain refinement mechanism of metallic materials produced by SPD was discussed.The effects of SPD techniques on strength

ductility and mechanical properties of the materials were analyzed

and influence rules of corrosion properties was also analyzed.The application of SPD for ultra-fine grained materials was prospected.
