Twinning suppressed at high strain rates
Increasing oxygen content from 0.2 to 0.4 wt% markedly suppresses {101‾2} tensile twin nucleation and growth while enhancing prismatic <a> slip, altering the high-strain-rate deformation mechanisms of titanium.

Both twinning and dislocation slip are significant in Ti-0.2O polycrystal
Dislocation slip predominates in Ti-0.4O polycrystal
Twin nucleation and growth markedly reduced in Ti-0.4O
Prismatic <a> slip more probable in Ti-0.4O
