High strength antithermal corrosion low segregation directional high temp alloy

This invention relates to high-strength thermal abrasion resistance high-temperoducre alloy with low segregation and directional solidification properties. Its constitutions are (wt.%): Co9-12, Cr11-16, Mo1-3, W4-7, Al4-7, Ta4-7, Ti0-2, Re2-3, C0.01-0.15, 0.005-0.02 and Ni as the rest. The heat treatment for directional solidification steps are: 1240+-10deg.C for 0.5Hrs; 1260+-10deg.C for 0.5Hrs; 1280+-10deg.C for 4Hrs; air cooling to room temperature; 1120+-10deg.C for 4-1 Hrs; slow cooling to 1080+-10deg.C for 4Hrs; air cooling to room temperature; 900+-10deg.C; air cooling to room lemperature. This invention alloy can meet the requirement strength for design of turbine blade of aircraft engine but also has excellent thermal abrasion resistance property. The plane with the turbine blade of aircraft engine can be used for high altitude flight and flight in corrosion environment obove turbine blade of aircraft engine can be used for high altitude flight and flight in corrosion environment above sea.
