Аннотация

It was shown that an increase in impact toughness of the Ti-6Al-4V alloy (including at low temperatures) was associated with two mechanisms. The first one was the suppression of the discontinuity nucleation due to the dynamic nature of the structural rearrangement provided by interstitial mesoscopic nanoscale structural states (IMNSS) under the crystal lattice curvature conditions as well as plastic distortion. The second mechanism was the ductile material extrusion in the superplastic flow mode (down to T = -70qC). This enabled to extensively deform specimens without failure (in fact, in the superplastic flow mode) upon impact bending. It was discussed that the development of deformation defect flows was realized according to the mechanism of the structural-phase transformation.
