Abstract:
A manufacturing apparatus for amorphous alloy in which molten metal, obtained by fusing a metal material with a high energy heat source which can fuse the metal material, is transformed into a predetermined configuration, the molten metal is cooled at over a critical cooling rate simultaneously with or after being transformed and molded into the predetermined configuration, comprising:a mold which is composed of a lower mold having a portion for fusing metal material and a cavity portion, and an upper mold which cooperates with the lower mold to press and flow the molten metal on the portion for fusing metal material into the cavity portion to mold; andthe portion for fusing metal material of the lower mold is composed of a material having heat conductivity equal to or less than 250 kcal/(m.multidot.h.multidot..degree. C.) andthe cavity portion of the lower mold is composed of a material having heat conductivity equal to or more than 270 kcal/(m.multidot.h.multidot..degree. C.).
