•: The twin nucleation rate increases with the deformation temperature and strain rate.
•: The deformation mechanism has changed at the higher strain rate (7025616304542&_mathId=si2.gif&_user=111111111&_pii=S0927025616304542&_rdoc=1&_issn=09270256&md5=7d5910ea9a6cf352e7206366e0d72b36">7025616304542-si2.gif"> $\dot{ε}$ ⩾ 10⁹ s^−1).
