Abstract

Commercially pure α- Ti has been plastically deformed by rolling to strains up to 97%. Optical and electron metallographic observations on the deformed material have then been related to changes in the hardness and texture. It is concluded that, at strains of up to 20%, strain twinning is the major mode of deformation, but at greater strains slip becomes dominant until eventually shear banding occurs at 94% strain. Even after 97% deformation the material is still ductile and the final texture forms independently of deformation twinning. The workhardening rate is lower than would be expected for fcc and bcc metals deformed at the same homologous temperature.
