Special features of formation of phase composition in alloys of the Ti – Cr and Ti – Cr – H systems are studied after hardening from the β-range (according to the equilibrium phase diagram of the Ti – Cr system) and long-term aging. The morphology of the precipitated phases is determined and schemes explaining the special features of formation of phase composition in hydrogen-containing alloys under aging are suggested. The microhardness characteristics of the alloys are shown to depend on their phase composition.
