Significantly increased twinning activity of pure titanium during room-temperature tensile deformation by cryogenic-deformation treatment

Pure titanium showed an exceptionally increased activity of twinning during tensile deformation at 298 K after being slightly rolled at 77 K, i.e., cryogenic-deformation treatment was performed. Thus, due to a twinning-induced hardening effect, the cryogenic-deformation treated material showed consi...

Description
Summary:Pure titanium showed an exceptionally increased activity of twinning during tensile deformation at 298 K after being slightly rolled at 77 K, i.e., cryogenic-deformation treatment was performed. Thus, due to a twinning-induced hardening effect, the cryogenic-deformation treated material showed considerably increased uniform ductility, which cannot be achieved in typical pure titanium.
