Within aviation engines, components such as fans, high-pressure compressor discs, and blades operate in complex environments characterized by high temperatures, pressures, and rapid rotations. Titanium alloys emerge as the optimal choice due to their outstanding high-temperature strength, resistance to creep, and oxidation properties. They exhibit remarkable stability in performance within the temperature range of 300 degree to 650 degree , ensuring the efficient operation of engines.
 

 

 

In China, significant advancements have been made in the application of titanium alloys. From the early stages with the J-10 fighter jet to the subsequent J11 series aircraft, the proportion of titanium alloys in aircraft structures has steadily increased. This progression not only enhances overall aircraft performance but also propels technological advancements within the country's aerospace industry. Furthermore, titanium alloys find widespread applications in aerospace products such as fuel tanks, projectile structures, and fasteners. To further promote the use of titanium alloys in the aerospace industry, China has established comprehensive aerospace titanium alloy standards. These standards encompass various aspects including research and development, production, inspection, and application of titanium alloys, providing robust support for their extensive utilization.
