The character and kinetic parameters of hydrogenation process of Ti—V system alloys are determined depending on their composition and initial state. Degree of hydrogenation for one heating—cooling cycle and the possibility of hydrogen capacity increasing due to sorption—desorption cycling is studied. The phase composition of (Ti, V)Hx hydrides produced under performed experimental conditions is also investigated. In the concentration range of vanadium 0.25—5 wt.%, a possibility to produce hydrides with high sorption capacity (H/Me = 2.18) is shown.

Key words: kinetic parameters of the hydrogenation, hydride, sorption, desorption, hydrogen capacity.
