Abstract

Ultrafine-grained (UFG) sheets of commercially pure (CP)-Ti were produced by equal channel angular pressing (ECAP), by ECAP plus subsequent rolling as a post-deformation and, for comparison, by rolling only, from coarse-grained (CG) billets. It was found that post-deformation of ECAPed CP-Ti by rolling achieves a higher strength with still considerable ductility, and a higher thermal stability compared with the sample's properties after ECAP deformation and/or rolling solely. Transmission electron microscopy investigations revealed that the post-deformed material has a finer and much more homogeneous microstructure than the rolled CG material. Besides, it was shown that the workability of ECAPed Ti depends on the purity.
