Creep performance in a CoNi-based single crystal superalloy with super-high γ′ volume fraction at 760 °C and equivalent high stress

Journal of Materials Research and Technology
The creep performance at low temperature and high stress is one crucial property for the single crystal superalloys widely used for turbine blades. In this study, the creep behavior of a CoNi-based single crystal superalloy with super-high γ′ volume ...

Superior creep resistance in a γ′-strengthened Co-based single-crystal superalloy at 760°C and ∼90% yield strength

Materials Research Letters
The creep mechanism of a Co-based single-crystal (SX) superalloy at 760°C/800 MPa (∼90% yield strength) was revealed and differed from those of Re-containing Ni-based SX superalloys.

Thin-wall debit effect on creep properties of single crystal superalloys

Journal of Aeronautical Materials
The thin-wall effect of single crystal superalloys refers to the phenomenon that when the thickness of the sample and the part is less than 1 mm，the lasting life is reduced， the creep rate is increased and other mechanical properties are significantly ...
