Abstract

The hydrogen absorption behavior of a Ti₆₀Zr₁₅Ni₁₅Cu₁₀ amorphous alloy was measured by using the conventional pressure-volume-temperature technique. It was found that under same temperature and pressure conditions the amorphous phase shows higher hydrogen absorbing capacity as compared with corresponding crystalline phase. Higher hydrogen to metal ratio H/M up to 1.41H/M can be achieved in the Ti₆₀Zr₁₅Ni₁₅Cu₁₀ amorphous alloy at room temperature, which is 17.6 times higher than that of the corresponding crystalline phase. The structure of the as-quenched and hydrogenated samples was examined by X-ray diffraction (XRD) and transmission electron microscopy (TEM). It is found that hydrogen absorption is accompanied by an expansion of the average nearest neighbor distance.
