Abstract

The transformation of crystal structure and twinning behavior for Ti-6Al-4V subjected to severe plastic deformation were studied. The face-centered cubic titanium in Ti-6Al-4V and the deformation twins in face-centered cubic titanium of Ti-6Al-4V were found via transmission electron microscopy and high-resolution transmission electron microscopy. And the deformation twins existed in the grain size of a few nanometers for equiaxed nanograins to about 150 nm in width for elongated ultrafine grains. In addition, the twinning mechanism was the partial dislocation emission from the grain boundary during the deformation of nanocrystalline face-centered cubic titanium.
