摘要
The mechanical properties of commercially pure (CP) Ti at room temperature were investigated. The decreasing grain size in CP Ti leads to significant increases in its hardness and/or strength. A combination of severe plastic deformation by high pressure torsion at 5 GPa followed by short annealing at low temperatures allows one to obtain a high strength (more than 1200 MPa) in pure material that is comparable in strength to alloyed Ti.
