Abstract: Under the conditions of the fast crystallization of melts, the effect of hydrogen on mechanisms of structural transformations in V₈₅Ni₁₅ and V_85-xTi_xNi₁₅ alloys was experimentally studied. Structuring of phase compositions, diffusion, and hydrogen permeability were simulated. The regularities of improving the structural characteristics of alloys as a result of alloying with titanium, as well as the effect of hydrogen dynamics on the stability of the formed phases are revealed.

Keywords: hydrogen, BCC phase, diffusion, permeability, simulation, multiparticle potentials, titanium alloys, microstructure, hybridization of polymorphic-phase transitions, membrane technologies, hydrides.
