| Riassunto: | Title screen Using methods of electron-microscopy and x-ray structural analysis, we have investigated peculiarities of the evolution of the structural-phase state of an alloy of the system Ti–Al–V–Мо during formation of an ultrafine-grained structure by a method combining hot plastic deformation and reversible hydrogenation. It has been shown that the presence in solid solution of 0.15 wt% hydrogen makes it possible to lower by more than a factor of 2 the magnitude of the plastic deformation needed to obtain an ultrafine-grained state in the alloy. We found that during deformation and subsequent degassing of hydrogen from the alloy, such processes as the phase transformations ???>?>? and ?>??? and a redistribution of the doping elements take place, facilitating the formation of a lamellar morphology in the grains and preservation of a high level of strength properties of the ultrafine-grained structure.
