摘要： Provided are: a closed-die forging method capable of preventing a temperature decrease in a to-be-forged member during forging, easy temperature monitoring during forging, and causing cavity end portions of a die to be filled with the to-be-forged member; and a method of manufacturing a forged article using the closed-die forging method. The closed-die forging method, which involves placing a heated to-be-forged member on a lower die and hammer-forging the to-be-forged member with a reciprocating upper die, includes covering the whole of a portion of the to-be-forged member that contacts the lower die with a metal heat-insulation member prior to forging, except for at least a part of a portion that contacts an upper die during forging, and then forging the to-be-forged member integrally with the metal heat-insulation member. Preferably, the to-be-forged member is a superalloy and the metal heat-insulation member is stainless steel. Further preferably, the to-be-forged member is forged into a disk shape. The method of manufacturing a forged article includes heat-treating a forged material obtained by the closed-die forging method at temperatures not lower than recrystallization temperature.
摘要翻译：本发明提供一种闭模锻造方法，其能够防止锻造时的锻造构件的温度下降，锻造时的温度监控变得容易，在模具的型腔端部填充被锻造材料会员; 以及使用闭模锻造方法制造锻造制品的方法。闭模锻造方法包括将加热的待锻造构件放置在下模上并用往复式上模锤锻造待锻造构件，所述闭模锻造方法包括覆盖待模锻构件的整个一部分，该锻造构件在锻造之前用金属绝热构件与下模接触，除了在锻造期间与上模接触的部分的至少一部分之外，然后将该锻造构件与该锻造构件一体地锻造金属隔热构件。优选地，待锻造构件是超级合金并且金属隔热构件是不锈钢。进一步优选地，锻造构件被锻造成盘状。制造锻造制品的方法包括在不低于再结晶温度的温度下对通过闭模锻造方法获得的锻造材料进行热处理。

摘要： Provided are a manufacturing method for a blade material and a manufacturing device for a blade material, by which a long blade material can be manufactured without using a large-sized press forging machine. A manufacturing method for a blade material, in which hot forging is sequentially performed by molds from the root side to a blade (vane) tip, wherein when a root-side portion is grasped and a material to be forged is restrained by a mold, twisting is performed on a region between the grasped portion and the restrained portion. A manufacturing method for a blade material, in which hot forging and twisting are repeated, is preferable, and a manufacturing method for a blade material, in which hot forging is performed while molds are sequentially changed, is more preferable.
