dc.description.abstractEnIn the context of cast alloy development for high temperature applications, high entropy superalloys (HESA) have exhibited superior cost specific tensile strength than that of superalloys such as CM247LC. Compositions of HESA are distinctively different from those of cast superalloys with higher contents of Fe and Ti, making HESA cheaper and lighter. Comparing to superalloys, although HESA has adopted the template of FCC-structured (γ) matrix and coherent L12-structured (γ′) precipitates, γ′ is enriched with solutes with higher intrinsic strength, rendering positive lattice misfit, and the high entropy γ matrix may have attributed to a good combination of strength and ductility.
