Abstract
Ultrafine-grained (UFG) metal materials processed by severe plastic deformation (SPD) have attracted the great interest. This overview introduces some attractive SPD techniques. Special attention is paid to two new deformation techniques named Elliptical Cross-section Spiral Channel Extrusion with Equal-area (ECSEE) and Elliptical Cross-section Spiral Channel Drawing with Equal-area (ECSDE). The mechanism and microstructure transformation characteristics of materials in SPD, current problems and ongoing research are also discussed in detail.
