ABSTRACT:
This invention relates to a method of manufacturing an article having a press-worked member inwardly of a cylindrical member, which comprises a first step for removing stain and oxidation film on the inner surface of a cylindrical member and on the peripheral side surface of a blank, a second step for arranging the blank inwardly of the cylindrical member so that the purified side surface of the blank may be faced toward the purified internal surface of the cylindrical member, a third step for subjecting the blank to a cold press-working inside the cylindrical member to thereby closely combine the blank with the cylindrical member, a fourth step for further subjecting the cold-worked blank to a hot press-working inside the cylindrical member to thereby form the blank into a desired shape within the cylindrical member, and a fifth step for annealing the combined members at a temperature for diffusion to thereby join the blank with the cylindrical member by diffusion. After that, a machining step such as cutting, milling or so on, is followed to provide a finished product of a desired shape. Also, such a machining step can be carried out between the fourth step and the fifth step.
