The severe plastic deformation on 1060pure aluminum at room temperature was carried outby accumulative roll-bonding, the microstructure evolution and mechanics performance change of 1060 industry pure aluminum before and after plastic deformation were studied.

Shot Peening(SP)is a typical severe plastic deformation method to produce ultra-fine grains of metallic materials.

After the brass specimen being subjected to ECAP, severe plastic deformations are occurred around the corner of die route and grain of brass is refined repeatedly.

Progress in developing superplasticity materials by severe plastic deformation;

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.

It is found that the precipitates are deformed, fragmented, and followed by dissolution into the matrix to form supersaturated solid solution in severe plastic deformation process.

ECAP(equal channel angular processing) is a processing procedure in which a sample is subjected to a very intense plastic strain by pressing it through a special die.

Under heavily drawn plastic deformation, we made nano-structured high strength pearlitic steel reinforced polymer urethanes composites, and investigated the composites' three-body abrasive wear mechanism.
