Abstract: A metallic material containing both a second constituent and a third constituent having positive and negative heats of mixing relative to a first constituent, respectively, and including a compound, an alloy or a nonequilibrium alloy having a melting point that is higher than the solidifying point of a metal bath made of the first constituent is placed in the metal bath. The metal bath is controlled to a temperature lower than a minimum value of a liquidus temperature within a range of compositional variations in which the amount of the third constituent in the metallic material decreases down to a point where the metallic material becomes substantially the second constituent so that the third constituent is selectively dissolved into the metal bath.

A carbon core formed into a shape of an external gear is arranged in a thin, long tubular mold of a length equal thereto with a space extending longitudinally therealong. A molten metal material is pressure-injected under a temperature higher than a melting point thereof into the space between the mold and the core. The molten metal material is resolidified by rapid cooling at or above a critical cooling rate thereof together with the mold and the core. After resolidification of the molten metal material, the core is removed by pulverization or dissolution. Along internal gear formed of the resolidified metal material is cut into a plurality of segments of a prescribed length.
