  • Publication number: 20180105909
    Abstract: Provided is a forging method for highly increasing hardness of a forged product as well as suppressing a decrease in the hardness in a use environment. The forging method includes a warm-forging step (S105) of warm-forging a metallic workpiece 10 which has been solutionized; and an artificial aging step (S106) of artificially aging the workpiece 10 after the warm-forging step (S105) in advance, at equal to an environmental temperature or higher than a temperature at which a product of the workpiece is used after production. Here, an equivalent plastic strain of the workpiece that increases between before and after the warm-forging step is in the range from 0.1 to 2.5.
