| Abstract: | The processes and principles on nano-structured materials prepared by severe plastic deformation(SPD) methods such as severe plastic deformation consolidation (SPDC) Equal Channel Angle Pressing(ECAP) and surface self-nanocrystallization are reviewed by analysis of the deformation characteristics.The intrinsic mechanism of grain fining in SPD process and the structure and performance features of the nano-material prepared by SPD method are analyzed.Also,the problems to be solved and the foreground in this field are proposed. |
