摘要
PROBLEM TO BE SOLVED: To provide a method for manufacturing an injection molding of an amorphous soft magnetic alloy which has excellent soft magnetic characteristics, has a large shape and has the structure amorphous over the entire part and a metal mold for injection molding which is capable of rapidly cooling injected molten metal without unevenness. ;SOLUTION: The method for manufacturing the injection molding of the amorphous soft magnetic alloy by injecting the molten metal into a toric cavity A from the tangent direction of the cavity A when manufacturing the injection molding 11 of the amorphous soft magnetic alloy by injecting the molten metal of a metal-glass alloy of ≥20 K in the temperature interval ΔTX of the supercooling liquid expressed by formula the equation ΔTX=TX-Tg (TX denotes a crystallization initiation temperature and Tg denotes a glass transition temperature) to the cavity A described above is adopted.;COPYRIGHT: (C)2001,JPO
