| Abstract: | DZ125 superalloy for DS thin wall hollow blades of advanced aero engines has been developed. It possesses high strength and strength and ductility comparable with the commercially other typical DS alloy such as PWA1422, CM247LC, DZ22 and DZ4. Also the alloy has excellent DS castability and less thin wall effect. The alloy has been used for producing complex DS blades of a aero engine and carrying out engine test. |
