The evolution and innovation practice of aviation forgings materials has always been a hot field in the aviation industry, and its development mainly includes the following aspects: Superalloy: Superalloy is one of the most commonly used materials for aviation forgings, and has good high temperature strength and creep resistance. With the increase of engine operating temperature, new superalloys, such as nickel base, cobalt base and iron base alloys, continue to emerge. These materials can further improve the high temperature performance and durability of forgings through the optimization of alloy design and heat treatment process. Superalloys: Superalloys are a class of metallic materials with special properties, usually composed of elements such as nickel, iron, cobalt and titanium. They have excellent high temperature strength, oxidation resistance and corrosion resistance, so they are widely used in aircraft engines. With the continuous improvement of aero-engine working conditions in recent years, the requirements for superalloys are also getting higher and higher, so the alloy formulation and treatment process have been continuously innovated and improved. Composite material: Composite material is a composite structure composed of two or more kinds of materials, the common fiber reinforced composite material. Some lightweight structures in aviation forgings have begun to use composite materials, such as carbon fiber reinforced composites. They have low density, high strength and good fatigue performance, and can be used to manufacture some important structural parts, such as turbine blades and fuselage components, to reduce engine weight and improve performance. Advanced Manufacturing technology: With the development of advanced manufacturing technologies, such as powder metallurgy, 3D printing and composite molding, the manufacturing process of aviation forgings has also been innovative and improved. These advanced manufacturing technologies can not only improve the manufacturing accuracy and consistency of parts, but also achieve the increase of design freedom, providing more possibilities for the performance optimization and improvement of aviation forgings. In general, the evolution and innovation of aviation forging materials is an ongoing process. Through the continuous innovation and application of superalloy, superalloy, composite materials and advanced manufacturing technology, aviation forging materials have made remarkable progress in high temperature, high pressure, high durability and other aspects, making important contributions to the improvement of aero-engine performance and flight safety.
