High density nano-scale twins in Cu induced by dynamic plastic deformation

Flaw-free bulk Cu specimens with a high density of nano-scale mechanical twins were produced by means of dynamic plastic deformation at liquid nitrogen temperature. The nano-twinned Cu exhibits a tensile yield strength of 600 MPa and an elongation-to-failure of 11%. The significant strengthening ori...
