In high‐entropy alloys (HEAs), the thermodynamics govern alloy formation, phase stability, and overall phase‐transition characteristics. Over the past decade, many thermodynamic parameters have been proposed for predicting the stability of HEA systems. Herein, analysis of these parameters are carried out carefully with the available data from the literature. It is found that all these parameters are not fully independent from each other and there exists a bridge of interconnection between them. Herein, inter‐dependency relationships between the thermodynamic parameters are derived for predicting the stability of solid solution in HEAs. It is found that parameters with large and complex equations are not essentially required; instead the simple parameters ϕ , Ω, and δ are sufficient for predicting the stability of HEA systems.
