330 _aStudies of the deformation and evolution of temperature fields in flat specimens of BT1-0titanium in the Coarse-Grained (CG) and nanostructured/ultrafine-grained (NS/UFG) states andBT6 titanium alloy were performed. The yield and ultimate stresses for NS/UFG BT1-0 titanium aretwice as high as those for the CG state and are comparable with the characteristics of the BT6 alloy. Itwas found that the ultimate strain before damage of NS/UFG titanium specimens that are tensionedat a constant deformation rate of 6.5 × 10-3 s-1 decreases by a factor of 2. In the region of a macro-scopic localization of a plastic deformation the temperature abruptly rises and reaches the maximumvalues in the crack formation zone. An abrupt temperature increase in the zones of localization of plas-tic deformations and crack formation is observed in specimens with both the CG and NS/UFG states.Comparing the experimental data on the temperature distributions on the surfaces of strained CG andNS/UFG titanium specimens shows that a macroscopic plastic deformation develops more uniformlyin BT1-0 titanium in the NS/UFG state. Under identical loading conditions, the heat release rate ishigher for BT1-0 titanium in the NS/UFG state
