The hydrogen absorption properties of V-Zr-Ti-M(M = Fe, Mn, Ni) alloys were examined in order to develop the alloys with high hydrogen capacity. It was found that the best composition among the studied alloys is the V-Zr-Ti-Ni system. A suitable amount of the vanadium in the V-Zr-Ti-Ni system was studied in correlation with its hydrogen absorption properties, and turned out to be around 75 at.%V. Substitution with Zr improved the hydrogen absorption properties in forming the grain boundary network phases of C14 Laves phase. Heat treating the alloys (homogenize and quench) drastically improves the plateau region of PCT curves. Zr addition also improves the properties for V-Zr-Ti-Cr alloys.
