摘要：在具有垂直分型面的铸模(1)中，各模腔(2，2′)通过一宽的喉管与补缩槽(3，11)相连。当铸模(1)浇铸后，通过一导管(15，19)给补缩槽(3，11)中的金属表面施加一气体压力。该气体压力不能超过铸模中该表面上的金属静压力，直到内浇口(4)中的金属凝固或内浇口被以其它方式阻塞。在导管(15，19)开口入补缩槽中的位置，导管由一不透过已浇铸的金属但透过压缩气体的元件(16，20)所覆盖。当内浇口(4)中的金属凝固或内浇口被以其它方式阻塞时，气体压力可增加。

摘要： 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 object 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.

摘要： A reduction casting method includes the steps of: pouring a molten metal into a cavity of a molding die; and performing casting while reducing an oxide film formed on a surface of the molten metal by allowing the molten metal and a reducing substance to come into contact with each other in the cavity. On this occasion, the molten metal is poured into the cavity in a state in which the molding die is forcibly cooled by a cooling device, thereby being rapidly cooled. Further, on this occasion, a solidification speed at which the molten metal is rapidly cooled is allowed to be 600° C./min or more. Still further, on this occasion, the molten metal is filled into the cavity in a filling time of from 1.0 second to 9.0 seconds.
