Abstract
Commercially pure Ti grade 2 was multi-directionally forged (MDFed) at room temperature. MDFing could be successfully carried out without any cracking to a cumulative strain of ΣÎεâ¯=â¯2.0. Ultrafine-grained (UFGed) structure gradually developed with increasing cumulative strain mainly by mechanical twinning and kinking. An average grain size of approximately 400â¯nm was attained. The mechanical properties were drastically modified by the grain refinement and a superior balance of tensile strength and ductility, 710â¯MPa and 21%, was achieved. Additional cold rolling of the UFGed Ti possessed further better mechanical properties of 930â¯MPa tensile strength and 19% ductility.
