摘要：
In this paper, we study the effect of the hydrogen presence in a solid solution on the stability of the structural and phase state and the mechanical properties of the ultrafine-grained titanium alloy of the Ti-Al-V-Mo system (VT16 grade) in the temperature range of 573-973 K in a vacuum and air. It was established that during annealing under conditions of hydrogen degassing from the ultrafine-grained structure, a beta -> alpha" -> alpha phase transfonnation and redistribution of alloying elements are observed, which contribute to the formation of a thin-plate (alpha + alpha" + beta) structure in beta grams and an increase in the mechanical properties of the alloy.
