From X-ray powder diffraction it was found that the synthesized alloy consists of two phases: HCP α and BCC β. Scanning electron microscopy (SEM) unveiled discernible surface characteristics on the Ti–55531 alloy, delineating two predominant phases with distinct variations in light and dark shades. These observed phases corresponded to microstructural compositions attributed to the α and β phases. The interaction of obtained Ti–55531 alloy with hydrogen in self-propagating high-temperature synthesis (SHS) mode was studied. It was demonstrated that the compacted alloy without preliminary crushing or mechanical treatment could absorb 3.4 wt % of hydrogen during the SHS process. Additionally, it was determined that the synthesized hydride of multicomponent alloy consists of two phases: TiH<sub>2</sub> phase with FCC structure and β-phase with BCC structure.
