Abstract

With the use of cryogenic deformations by rolling and quasi-hydroextrusion, as well as annealing up to 723 K, various structures, including nanometer ones, were created in ultrafine-grained (UFG) titanium alloy of the VT6 grade, and mechanical and dissipative properties were studied. The deformation regimes for the formation of a nanostructured state with a high level of strength characteristics without loss of plasticity are established. The revealed features of the temperature dependences in the range of 100…600 K of internal friction and shear modulus in the nanostructured state in comparison with the UFG state are analyzed.
