Table 2 Properties of pure elements constituting the AlCo1−xFeNiTiMox (x = 0, 0.1, 0.25, 1.0) HEAs (the metallic atomic radius (r), the melting temperature (Tm), average valence electron concentration (VEC) and the Pauling electronegativity (χ) and structure. The atomic radius, average valence electron concentration, and Pauling electronegativity are taken from Ref34.
