摘要

PROBLEM TO BE SOLVED: To provide a method for producing a forging-formed article with which even in the case of being a material having difficulty to work, this material can be forged.;SOLUTION: In the method for producing the forging-formed article having thick portions at both sides in the forging direction of the center portion; after performing a first forging process for obtaining a preliminary formed article formed to almost finish shape at one side of the thick portion by using an aluminum alloy-made material having difficulty to work as a blank for forging, since a second forging process for forming to the finish shape at the other side of the thick portion while keeping the contacting state over the whole range of the one side of the preliminary formed article and a die, even in the case of using the material having difficulty to work as the blank for forging, since the forging-formed article can be formed under state of no developing of the free forging surface at the one side of the thick portion, the formed article having no crack can be obtained. Further, since the excess thickness for preparing the development of crack is not needed, there is no necessity for removing the excess thickness portion by machining, and thus, good yield of the material is obtained.;COPYRIGHT: (C)2007,JPO&INPIT
