The hydrogen absorption property of a Ti60Zr15Ni15Cu10 amorphous alloy is presented. The maximum hydrogen concentration of the amorphous alloy was 1.41H⁄M at room temperature. The hydrogen absorption at lower temperatures with higher H2 pressures favored higher H/M ratios for the amorphous alloy without any crystalline hydride growth. The structures of the as-quenched and hydrogenated samples were investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The absorption was accompanied by expansion of interatomic spacing in the amorphous structure. The hydrogen storage ability of the Ti60Zr15Ni15Cu10 amorphous alloy was found to be better than that of the related crystalline phase in this system.
