Co-Al-W-based superalloys may become a next generation of high-temperature structural materials used in the hot-section of gas turbine because of the discovery of γ\'-strengthening mechanism.The current understanding of deformation behavior and creep properties of Co-Al-W-based superalloys is reviewed in this study.It is found that the Co-Al-W-based superalloys have strong anomalous yield stress behavior and better creep properties,making it as an attractive candidate for high-temperature structural material.The relationship between deformation/creep microstructure and the properties of the alloys needs to be further clarified,which can provide deeper theoretical guidance for further composition design,optimization of heat treatment processes,and guidance of alloy service.
