Abstract
A quaternary alloy consisting of zirconium, titanium, manganese and iron is characterized in having C14 hexagonal crystal structure and ZrMn.sub.2 stoichiometry. Members of a preferred class of compounds, represented by the empirical formula Zr.sub.1-x Ti.sub.x Mn.sub.2-y Fe.sub.y wherein "x" has a value between 0.05 and 0.3 and "y" has a value between 0.1 and 1, are particularly suitable for use as hydrogen storage materials.
