Abstract—The influence of thermohydrogen treatment combined with hot rolling on the structural formation in α- and near-α-titanium alloys has been studied. The prospects of obtaining submicron-grained sheet semifinished products of VT5 (Ti–5.8Al–0.1Fe, wt %) and VT20 (Ti–5.9Al–1.5V–1.2Mo–1.8Zr–0.1Fe, wt %) alloys are shown. In these materials, a submicron-grained structure allows the plastic deformation to be induced by superplasticity at temperatures reduced by 100–200°С.

Keywords:

titanium alloys hydrogen technology submicron-grained structure superplasticity flow stress electron microscopy fine structure

ACKNOWLEDGEMENTS

This work was partially supported by the Russian Foundation for Basic Research (project no. 16-32-00175-mol_a dedicated to high-resolution electron microscopy of the thermomechanical stability of microstructure in the presence of alloying elements and project no. 16-32-50052-mol_nr considering the state-of-the-art electron microscopy characterization of phase composition of titanium alloys with alloying elements).

The study was performed within the framework of the complex scientific program 10 “Energy-Efficient, Resource-Saving and Additive Technologies of the Fabrication of Details, Semifinished Products and Structures” (Strategic Directions of the Development of Materials and Technologies for Their Recycling for the Period to 2030).

We express our deepest gratitude to A.A. Il’in, Academician of the Russian Academy of Sciences and one of the founders of hydrogen titanium alloys technology in Russia, as well as to his colleagues Profs. S.V. Skvortsova and A.M. Mamonov, for their kind assistance and mentorship in acquisition and interpretation of experimental data.
