Detailed thermal activation analysis has been carried out on experimental data for the plasticity of polycrystalline titanium containing 0.06-1.6at.% O in the temperature range 4.2-600 K. The analysis of the dislocation-impurity interaction parameters took into consideration the variations in the shear modulus and internal stress with temperature and the fact that the impurity distribution along dislocations can have various statisfies. Values of the energy and maximum force of the dislocation-impurity interaction, the «depth» of the obstacle (the interaction region), the pre-exponential factor in the Arrhenius equation, as well as the average dislocation segment length and the internal stress, have been determined.
