Figure 6. Relationship between element features and Ept: (A) covalent radius, (B) electronegativity, (C) DFT volume and (D) melting point. Blue elements correspond to negative Ept values, whereas brown elements correspond to positive Ept. The vertical dashed line in each plot represents the corresponding value for Al. Ept: Phase transformation energy; DFT: density functional theory.
