Abstract

The invention discloses a heat treatment technique for an additive component. The heat treatment technique for the additive component is used for improving the overall mechanical performance index of the additive component. The heat treatment technique for the additive component comprises the following steps of annealing, specifically, annealing treatment is conducted on the additive component; and quenching, specifically, quenching treatment is conducted on the annealed additive component twice, low-temperature quenching is conducted on the additive component firstly, and then high-temperature quenching is conducted on the additive component. By adoption of the heat treatment technique, the overall mechanical performance index of the additive component can be improved, and the using requirements in the aviation field are met.

Description

technical field [0001] The present application relates to the technical field of heat treatment, in particular to a heat treatment process for additive components. Background technique [0002] Additive manufacturing, commonly known as 3D printing, is the process of accumulating special metal materials, non-metal materials and medical biomaterials layer by layer according to extrusion, sintering, melting, light curing, spraying, etc. through software and numerical control system to manufacture physical objects. Manufacturing Technology. The emergence of additive manufacturing technology has made it possible to manufacture complex structural parts that were previously restricted by traditional manufacturing methods and could not be realized. [0003] At present, the domestic heat treatment process for additive components is mainly based on experience trial and error based on the traditional casting and forging heat treatment process. However, the additive components process...
