The hydrogen-sorption properties of the composite consisted of Ti$_{47.5}$Zr$_{30}$Mn$_{17.5}$V$_{5}$ ingot and Mg powder is investigated. As found, the presence of magnesium powder does not affect the hydrogen sorption—desorption kinetics of bulk heterophase Ti$_{47.5}$Zr$_{30}$Mn$_{17.5}$V$_{5}$ alloy. As shown, the bulk Ti$_{47.5}$Zr$_{30}$Mn$_{17.5}$V$_{5}$ alloy is crushed into hydrides’ powder upon hydrogen sorption. The presence of the obtained hydrides’ powder led to partial hydrogenation of magnesium powder at a temperature of 340—420°C and a hydrogen pressure of 0.018 MPa.

Key words: magnesium powder, heterophase alloy, hydrogenation, dehydrogenation, hydrogen capacity.
