Abstract
Quarternary alloys of the formula: Zr.sub.1-x Ti.sub.x Cr.sub.1-y Fe.sub.1+y are provided, which are characterized as having C14 hexagonal Laves phase wherein "x" has a value between 0.05 and 0.1 and "y" has a value of 0 to 0.4. These alloys, have P-C-T relations with low hysteresis and flat plateaux, are suitable for various applications such as hydrogen storage and hydride heat pump system.
