Abstract (en)

Provided are a method of molding an amorphous alloy, which has a high degree of work freedom regardless of components of an amorphous alloy, in particular, metallic glass and of the shape of an article to be molded, and is capable of producing a molded article having less pores, and a molded obj ect produced by the molding method. The method of molding an amorphous alloy includes: a melting step of melting an amorphous alloy; a differential-pressure casting step of injecting a melt of the amorphous alloy into a casting mold positioned below the melt and evacuating the casting mold; and a processing step of processing the melt by heating and pressurizing the melt in the casting mold while keeping the melt in a supercooled state.
