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 ...

Alloy design integrating natural language processing and machine learning: breakthrough development of low-cost, high-performance Ni-based single-crystal superalloys

npj Computational Materials
The traditional design of single-crystal superalloys relies heavily on trial-and-error experimentation, which is time-consuming and costly. Here, we present an intelligent alloy design strategy that integrates natural language processing (NLP) and ...
