摘要： To produce a hydrogen storage alloy by melting a hydrogen storage alloy having a body-centered cubic crystal structure without using a refractory crucible and solidifying a molten alloy by a unidirectional solidification process. The unidirectional solidification is carried out by a cold crucible induction melting method at a moving speed of a solid-liquid interface in the range of 10 to 200 mm/hr by using a water-cooled metal crucible in a vacuum or an inert gas atmosphere.

摘要： An object of the present invention is to obtain an ingot containing homogeneous ingredients with suppressing ingredient segregation of Y in the melt-production of an Mg alloy containing Y.An ingot is formed in a solidification time of not more than 200 seconds after an Mg alloy containing Y is melted. The above solidification is desirably performed after the melt liquid of the Mg alloy is stirred and left standing. The above Mg alloy, for example, contains Y in an amount of 0.5 to 20% by weight. There is an advantage that an Mg alloy having low ingredient segregation and containing homogeneous ingredients is obtained. Therefore, in the production of alloys whose performance considerably varies depending on the ingredient concentration, such as functional materials, high-quality products can be produced in good yield rates. In order to achieve the above object, specifically, the raw material is melted in a melting furnace and, after melt drop, the melt liquid is sufficiently stirred and left standing. Thereafter, it is cast into a mold designed so that solidification is completed within the above-defined solidification time. Moreover, it is also possible to shorten the solidification time by casting the melt liquid into a sufficiently water-cooled mold.
