Aviation forging technology has been constantly developing and innovating, and the application from conventional materials to super alloys can be said to be an important milestone for aviation forging technology to enter a new era. Limitations of conventional materials: Traditional aviation forgings are mainly made of high-strength steel or aluminum alloys, which have good strength and reliability, but face limitations under some extreme environmental conditions. Extreme conditions such as high temperature and high pressure will cause the mechanical properties of conventional materials to decline and cannot meet the requirements of aircraft for strength, stiffness and wear resistance. Advantages of superalloys: Superalloys are a class of metal materials with excellent high temperature strength and corrosion resistance, capable of performing well in extreme environments. Compared to conventional materials, superalloys have higher temperature strength, better oxidation resistance and heat fatigue properties, making them ideal for the field of aviation forgings. Application of superalloys: The introduction of superalloys has brought many new applications and innovations to aviation forging technology. For example, in the high-temperature components of the engine, such as turbine blades, combustion chambers, etc., conventional materials can not meet the requirements, and super alloys can withstand high temperature and high pressure working conditions; In aerospace, superalloy forgings are widely used in key components such as turbine engines, turbochargers, and jet thrusters, improving the performance and reliability of aircraft. Superalloy forging technology: The forging process of superalloy is the key to the new era of aviation forging technology. Superalloys have a high melting point and plastic deformation temperature, requiring the use of advanced thermal processing technology to achieve forging. At present, the commonly used superalloy forging technology includes equal diameter deformation forging, isothermal forging, superplastic forming, etc. These technologies can ensure the uniformity of materials, fine grains and reduce defects, and improve the performance and quality of superalloy forgings. Alloy design and development: The application of super alloy forgings also involves the design and development of alloys. The strength, toughness and heat resistance of the superalloy can be improved by optimizing the proportion of the alloy and controlling the microstructure. The innovation in alloy design provides a broader space for the development of aviation forgings technology. In summary, the application from conventional materials to superalloys is an important milestone for aviation forging technology to enter a new era. The excellent performance of superalloy and advanced forging technology provide a reliable solution for the high temperature and high pressure working conditions of aircraft, and promote the continuous innovation and development of aviation forging technology.
