Wrought superalloy has been widely used in hot section parts such as liquid rocket engine thrust chambers,turbine shells and turbine rotors because of its excellent high-temperature resistance,oxidation resistance,thermal corrosion resistance as well as good cold and hot workability.The develop-ment status of wrought superalloy and thermal processing technology,the performance requirements of wrought superalloy for hot section components of liquid rocket engines,and the application of wrought su-peralloy in well-known liquid rocket engines are reviewed based on domestic and foreign literature.Based on the development trend of reusability,high performance,light weight and low cost of liquid rocket en-gines,the main development trends of wrought superalloy in liquid rocket engines have been summarized.To improve the performance of superalloy and reduce the cost of manufacturing by investigating superalloy materials aiming at service conditions of liquid rocket engines and improving the hot working processes.On the other hand,more attention can be paid to developing and promoting high-temperature resistant lightweight intermetallic compounds to reduce the weight of hot section components.
