Abstract

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 ȕ ĺ Ds ĺ D phase transformation and redistribution of alloying elements are observed, which contribute to the formation of a thin-plate (D + Ds + ȕ) structure in ȕ grains and an increase in the mechanical properties of the alloy.
