The heat treatment process of aviation forgings mainly includes the following: solution treatment: solution treatment is to heat the forgings to a certain temperature for a period of time, and then quickly cool. This process is mainly used to adjust the structure of the forging, eliminate the stress generated during forging, and improve the strength and toughness of the material. Quenching treatment: Quenching is to heat the forging to a critical temperature above, and then quickly cool to room temperature or low temperature. Quenching can form a hard structure on the surface and inside of the forging, improve hardness and wear resistance, but reduce its toughness. Fine-tuning treatment: Fine-tuning treatment is to reheat the forging after quenching and then gradually cool it. This process can achieve the desired mechanical properties and corrosion resistance of forgings by regulating the recrystallization process and the precipitated phase. Tempering treatment: Tempering is to heat the quenched forging to a certain temperature for a period of time, and then gradually cool. Tempering can eliminate the internal stress generated during quenching and improve the toughness and plasticity of forgings. The above are some commonly used heat treatment processes for aviation forgings, and the specific selection and parameters need to be determined according to the material, shape, size and requirements of the forgings in practical applications. Therefore, before heat treatment, comprehensive analysis and testing are needed to ensure the best performance and quality.
