The microstructure and phase composition of cast (Ti$_{0.34}$Zr$_{0.66}$)Mn$_{1.1}$V$_{0.1}$ alloy as well as its phase composition in hydrogenated conditions are studied by optical microscopy and X-ray phase analysis. As found, the vanadium addition does not affect the hydrogen sorption kinetics. As shown, the increasing of both the hydrogen capacity of the alloy and the thermal stability of the resulting hydride is associated with the redistribution of atoms in tetrahedral pores.

Key words: Laves phase, tetrahedral pores, hydrogenation, dehydrogenation, hydrogen capacity.
