Research Status and Prospects of Materials for Aero-engines in China

Aero-engine, a highly complex and precise thermal machinery, is the engine that provides the aircraft with the necessary power for flight. As the heart of aircraft, it directly affects the performance, reliability, and economy of the aircraft, and it is also an essential embodiment of a country’s scientific, technological, industrial, and national defense strength. Thus, this paper compares the material, structure, and process characteristics of China’s aero- engines and the development process and research status of high-temperature alloys in the field of aero-engines. Finally, some prospects are put forward for the development of aero-engine materials.
