Abstract

The progress in effective factors and the grain refinement mechanism in ECAP was summarized. The effects of the pressing temeprature and speed on the materials during ECAP were discussed. The effects of deformation approaches and times on grain size and deformation degree of the materials were reviewed briefly. Approaches to present status of the ultra-fine grain materials processed by ECAP were performed and some further research issues were proposed.
