In the forging process, it is necessary to reasonably control the heating temperature, holding time, forging ratio and other parameters to ensure the plasticity and toughness of the alloy. In addition, proper heat treatment is required to obtain the best mechanical properties and corrosion resistance.
2.alloying elements.
Inconel 686 nickel-based alloy contains a variety of alloying elements, such as chromium, molybdenum, aluminum, etc., which have a significant impact on the properties of the alloy. For example, chromium can improve the corrosion resistance of alloys, molybdenum can improve the strength and hardness of alloys, and aluminum can improve the oxidation resistance of alloys. Therefore, in the production process, it is necessary to reasonably control the content of alloying elements according to the actual demand.
3.Heat treatment process.
The heat treatment process is one of the important factors affecting the performance of inconel 686 nickel-based alloy forgings. Through the appropriate heat treatment process, the microstructure and microstructure of the alloy can be changed, thereby improving its mechanical properties and corrosion resistance. For example, the strength and hardness of the alloy can be improved by high-temperature solution treatment and aging treatment, while maintaining good plasticity and toughness.
III. Conclusion. Inconel 686 nickel-based alloy forgings have excellent high temperature resistance, corrosion resistance and oxidation resistance, so they are widely used in aviation, aerospace, chemical industry and other fields. In the production process, it is necessary to reasonably control the parameters such as forging process and heat treatment process to ensure the performance and quality of Inconel 686 nickel-based alloy forgings. At the same time, for different application scenarios, it is necessary to select appropriate processing methods and performance indicators according to actual needs to meet the design requirements.
