The microstructure and phase composition of a cast Ti$_{15.4}$Zr$_{30.2}$Mn$_{44}$V$_{5.4}$Сr$_5$ alloy obtained using titanium sponge, as well as the phase composition of hydrogenation product, are investigated by scanning electron microscopy and X-ray phase analysis. As found, the complete replacement of expensive iodide titanium with a relatively cheap titanium sponge does not affect the structure and phase composition of the alloy. As shown, the saturation of the alloy with hydrogen occurs at room temperature and pressure of hydrogen of 0.21 MPa in a short time up to a capacity of 2.12% mass.
Key words: Laves phase, titanium sponge, hydrogenation, dehydrogenation, hydrogen capacity.
