METHOD FOR MOLDING AMORPHOUS ALLOY AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To easily produce amorphous molded parts with various deformed shapes including a one-face-opened or through type hollow shape free from cavities and having an extremely high solid degree. SOLUTION: A method for molding amorphous alloy comprises: a melting step where an amorphous alloy (1) is subjected to levitation melting; a tapping step where the molten metal (1b) of the amorphous alloy (1) is tapped to a lower casting mold located below the molten metal (1b); and a pressure rapid cooling step where an upper casting mold (1b) is pressed against the lower casting mold (2), and the molten metal (1b) in the lower casting mold (2) is pressed. In this way, the exhaust of gas occluded in the molten metal is performed by the rapid cooling and pressurizing of the molten metal, thus a sound amorphous metallic member free from cavities and having a free shape can be molded.
