A high strength low ductile alloy is formed in a desired shape with high accuracy by bundling a multiplicity of fine wires made of the high strength low ductile alloy, consolidating the bundle of fine wires into a prescribed shape thereby giving rise to a formed product wherein the interiors of the fine wires comprises aggregates of very fine grains resulting from primary recrystallization and subjecting the formed product to thermal treatment for grain growth at the temperature of secondary recrystallization whereby the very fine grains undergo grain growth. |
