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 (delta), electronegativity difference (Delta chi), mixing entropy (Delta S (mix)), entropy of fusion (Delta S (f)), and mismatch entropy (S (sigma) ). In continuation of that, two new parameters (a) Modified Darken-Gurry parameter (A = S sigma * chi) and (b) Modified Mismatch Entropy parameter (B = delta* S sigma) have been designed to predict the stable crystal structure that would form in the HEA systems considered for assessment.
