. The results show that the CP-Ti processed by severe plastic deformation still has ability for work hardening and can be strengthened again. The main reason of such strengthening probably caused by the variation of the microstructures results from the dynamic recovery occurred during further plastic deformation. Key words: commercial purity Ti; severe plastic deformation; strength; work hardening 由于具有高......
