Critical raw material-free multi-principal alloy design for a net-zero future.

ABSTRACT: Refractory High-Entropy Alloys (RHEAs), such as NbMoTaW, MoNbTaVW, HfNbTaZr, Re_0.1Hf_0.25NbTaW_0.4, Nb₄₀Ti₂₅Al₁₅V₁₀Ta₅Hf₃W₂, Ti_xNbMoTaW (x = 0, 0.25, 0.5, 0.75 and 1), and 3d transition metal HEAs such as Al_10.3Co₁₇Cr_7.5Fe₉Ni_48.6Ti_5.8Ta_0.6Mo_0.8W_0.4 have demonstrated superior performance compared to traditional superalloys, particularly in high-temperature applications for engine components. However, the development of these alloys often depends on critical raw materials (CRMs) such as Ta, W, Nb, Hf, and others. The reliance on critical raw materials (CRMs) not only generates
