Abstract
The temperature dependences of the offset yield strength, strain-rate sensitivity of deformation stress, and the activation volume of plastic deformation in VT1-0 nanocrystalline titanium, have been determined under quasistatic tension in the temperature range 4.2–395 K. Thermal activation analysis of experimental data has been performed. The low-temperature plasticity of nanocrystalline titanium is shown to be controlled by the thermally activated passage of dislocations through local barriers formed by interstitial impurity atoms. The empirical values of the theoretical parameters of the dislocation–impurity interaction have been determined.
