“…The microstructures of the blade materials are degraded during the service under the coupling effect of temperature and stress, including the evolution of the morphology of the γ′ precipitates and defects (Agudo Jácome et al, 2014;Gan et al, 2020;He et al, 2021) as well as transformation of carbides and precipitation of a topological close-packed phase (TCP) (Zhang et al, 2020). At present, the research on the turbine blades mainly focuses on the relationship among the microstructure (Link et al, 2011;Dubiel and Czyrska-Filemonowicz, 2012;Avila-Davila et al, 2018), service environment (Aurrecoechea et al, 1991;Miura et al, 2010;Chen et al, 2016a;Huang et al, 2018;Fu et al, 2020) and material properties (Fu et al, 2019;Huang et al, 2019;Ren et al, 2021) of the blade.…”
