Deformation features and affecting factors of a Re/Ru-containing single crystal nickel-based superalloy during creep at elevated temperature

By means of creep properties measurement and contrast analysis of dislocation configuration, the deformation features and affecting factors of a Re/Ru-containing nickel-based single crystal alloy during creep is studied. Results show that the creep life of alloy at 1040 °C/160 MPa is measured to be 725 h to display a good creep resistance. During creep, the W, Re atoms in γ′ phase may be excluded for enriching in the γ phase near the interface,...
