Abstract Scope |
During the manufacturing process of Ni-based single crystal superalloy components, unexpected plastic deformation can occur. Plastic pre-deformation between solution and aging heat treatments can be detrimental to the material’s creep and fatigue lives at temperatures above 950 °C, which has been observed in the previous studies. In this study, different types of pre-deformation were introduced to a Ni-based single crystal superalloy and material’s creep life has been evaluated. Rejuvenation treatment method was applied to restore the microstructure and the mechanical properties of different pre-deformed materials. Conditions for successful rejuvenation treatment will be presented for different Ni-based single crystal superalloys, AM1 and CMSX-4 Plus. |
