Ni-Ti intermetallic compounds are produced by subjecting a laminate of Ni foils and Ti foils to a rolling for thickness adjustment and then to a diffusion heat treatment at multistages within a particular temperature range for a particular time.

A rare-earth metal series alloy for storage of hydrogen is represented by a general formula of Rem.sub.1 Ni.sub.w Al.sub.x Fe.sub.y M.sub.z as an atomic ratio (wherein Rem is at least one rare earth element such as Mischmetal, M is at least one of Cu, Nb, Si and Zr, and 2.5&lt;w&lt;5.5, 0&lt;x&lt;2.0, 0&lt;y&lt;2.0, 0&lt;z&lt;2.0 and 4.0.ltoreq.w+x+y+z.ltoreq.6.0). Further, the alloy is coated with a film of at least one of Pd, Cu and Ni having a thickness of 100-1000 .ANG..

A wide thin metal sheet having a smooth surface may be manufactured directly from molten metal. A lower end of a nozzle installed vertically at the bottom of a molten metal vessel is held in contact with an inclined plate made of a refractory material, molten metal is discharged in a fan-shape from a notch formed in the peripheral wall of the nozzle end, the discharged molten metal being rendered into a constant shape laminar flow having a uniform flow rate distribution on the inclined surface as it flows down the inclined plate. The constant shape laminar flow is supplied to a molten metal pool between a pair of rollers of internally water-cooled type without any disturbance on the surface and in the inside. The metal solidified in the neighborhood of a portion of the gap between the two rollers is discharged from an open-at-the-bottom space defined between the two rollers.
