Abstract :
The type of deformation twins in purity titanium after dynamic plastic deformation (DPD) and quasi-static compression (QSC) at room temperature is investigated by electron backscatter diffraction techniques, respectively. DPD with a high strain rate (4.5–5 × 102/s) activates more deformation twins in Ti. Four types of twins have been identified in DPD samples, while three types of twins in QSC samples. The { 1   1   2 ¯   4 } twinning is only observed in DPD samples, associating with the { 1   1   2 ¯   2 } twinning. The misorientations of { 1   1   2 ¯   2 }–{ 1   1   2 ¯   4 } variant pairs are 12–13°, suggesting they follow the same misorientation profile ( 0   1   1 ¯   0 ) plane and rotated direction.
