A method and device for heating and forging a superalloy

Abstract

The embodiment of the invention provides a high-temperature alloy heating forging method and device. The high-temperature alloy heating forging method comprises the steps that the design requirement of a target forge piece is obtained; according to the first corresponding relation between the design requirement and the high-temperature heating temperature, the high-temperature heating temperaturecorresponding to the design requirement of the target forge piece serves as the high-temperature heating temperature of the target forge piece; according to the second corresponding relation between the design requirement and the blank-making deformation amount, the blank-making deformation amount corresponding to the design requirement of the target forge piece serves as the blank-making deformation amount of the target forge piece; and according to the third corresponding relation between the design requirement and the forming deformation amount, the forming deformation amount correspondingto the design requirement of the target forge piece serves as the forming deformation amount of the target forge piece. According to the high-temperature alloy heating forging method, the finally required demand of the forge piece can be met, and large resource waste caused by product scrapping is reduced.

Description

technical field [0001] The invention belongs to the field of forging thermal processing, and relates to a method and a device for heating and forging a superalloy. Background technique [0002] The GH4169 alloy is a precipitation-hardening nickel-chromium-iron-based deformation superalloy with a body-centered cubic Ni3Nb (γ") phase and a face-centered cubic Ni3 (Al, Ti, Nb) (γ') phase. It has high yield strength, good thermal processing plasticity, oxidation resistance, radiation resistance, fatigue resistance, and excellent welding performance. And the internal structure required by forging can be realized by forging deformation after heating. [0003] The types of forgings that can be produced after heating the alloy are: standard industry, high-strength process, and direct aging process. Among them, the high-strength process and direct aging process are used for high-quality GH4169 alloy forgings, but the determination of the heating temperature of the forgings will affec...
