Abstract

In the work, we studied and compared the microstructures of commercially pure copper subjected to the same strain at room temperature and at liquid-nitrogen temperature. It is found that at rather low plastic strain (slump, e=1.0), cryogenic temperature assists the activation of mechanical twinning and somewhat accelerates the formation of deformation boundaries. At high plastic strain (high-pressure shear, e=8.4), cryogenic temperature adds too little to microstructure refinement.
