“…For the study, samples were prepared in different microstructural states: cast material, samples produced by electron beam melting (EBM Ti-6Al-4V alloy), and samples obtained using methods of severe plastic deformation (UFG Ti-6Al-4V alloy). Samples in the cast state were annealed at a temperature of 750 • C. The EBM Ti-6Al-4V samples were built using an electron-beam melting 3D-printer designed in Tomsk Polytechnic University [15]. The Ti-6Al-4V powder was supplied by "Normin" Ltd. (Russia), the average particle size of the powder was 70 µm.…”

The defect structure of annealed cast, electron beam melted and ultrafine-grained titanium Ti-6Al-4V alloys before and after hydrogenation was studied. It has been established that before hydrogenation the predominant types of defects in electron beam melted and ultrafine-grained titanium alloy are dislocations and low-angle boundaries, respectively. The cast alloy after annealing is defect-free material. Hydrogenation from the gas phase to 1.00 ± 0.15 wt% leads to an increase of the concentration of the predominant type of defects. Moreover, vacancy complexes also presented in electron beam melted and ultrafine-grained Ti-6Al-4V alloys interact with hydrogen and form hydrogen-vacancy complexes.
