Abstract
An effort has been made to reassess the phase predicting capability of various thermodynamic and topological parameters across a wide range of HEA systems. These parameters are valence electron concentration, atomic mismatch (δ), electronegativity difference (Δχ), mixing entropy (ΔS mix), entropy of fusion (ΔS f), and mismatch entropy (S σ ). In continuation of that, two new parameters (a) Modified Darken–Gurry parameter (A = Sσ * χ) and (b) Modified Mismatch Entropy parameter (B = δ* Sσ) have been designed to predict the stable crystal structure that would form in the HEA systems considered for assessment.
