Conduct chemical composition analysis, mechanical performance testing, etc. on the selected materials to ensure they meet the requirements.
    2. Forging:
For large and thick components, forging process is adopted. This includes the following steps:
The nickel alloy billet is heated to an appropriate temperature, usually within its thermoplastic range.
Place the heated billet in the forging die and apply pressure to form a predetermined shape.
After completion, heat treatment is carried out to eliminate internal stress and improve the mechanical properties of the material.
    3. Casting:

For complex shaped parts or large-scale production, casting technology is often used. The specific steps include:

• Prepare suitable casting molds and perform surface treatment to ensure smooth casting surfaces.
• Heat the nickel alloy to its melting point and inject the molten metal into the mold.
• Control the cooling rate to avoid defects and ensure that the castings have the required size and performance.

    4. Machining:
For parts that require precise dimensions and surface quality, machine them. Common machining processes include:

• Turning: Cutting the workpiece into the desired shape by rotating the tool.
• Milling: The process of using a rotating tool to cut the desired shape on the surface of a workpiece.
• Drilling: Using a drill bit to form holes inside the workpiece.

    5. Welding:
Assemble or repair parts using appropriate welding methods. Common welding methods include:

• TIG (argon arc welding): Heating the surface of the workpiece through an arc and welding the area with inert gas protection.
• MIG (Metal Inert Gas Welding): During the welding process, continuous electrode wires are used and inert gas is automatically sprayed to protect the welding area.

    6. Heat Treatment:
Improve the structure and properties of materials by controlling the heating and cooling processes. Including:

• Annealing: Heat to an appropriate temperature and slowly cool to reduce internal stress and improve toughness.
• Solution treatment: Heat the alloy to solution temperature and then rapidly cool to improve strength and hardness.

    7. Surface Treatment:
Treat the surface of the parts to improve corrosion resistance and aesthetics. This includes:

• Polishing: The process of grinding or polishing to make the surface smooth and flawless.
• Chemical treatment: Using a chemical solution to treat the surface to improve its corrosion resistance.

    8. Quality inspection and testing:
After processing, strict quality inspection and testing are carried out on the parts. Including:

• Dimensional inspection: Use measuring tools to ensure that the dimensions of the parts meet the design requirements.
• Material performance testing: Evaluate the mechanical properties of materials through tests such as tension and hardness.
• Ultrasonic testing: detecting internal defects such as pores and inclusions
