Dilatational strain biplots against enthalpy of mixing for predicting high-entropy alloys and complex concentrated alloys phase stability

Multiple principal component alloy systems are a new class of alloys that can provide interesting combinations functional and mechanical properties. Due to the multiple components, their interactions complex, structural stabilities often not easily predicted. Prediction parameter biplots offer good way distinguish between different compositions. The enthalpy mixing is one used in such biplots. Although it does accurately follow quantum principles, nevertheless this deviation gives its predictive power when combined with other parameters biplot. This be part attributed strain energy (from large atomic size difference) may present systems. Such biplot leverage on expected deviations prediction scheme. Here, we investigate efficacy enthalpy-of-mixing/strain-energy using cluster analysis. results validated against enthalpy-of-mixing/valence electron concentration investigated only maintains ability intermetallic solid solutions phases but offers enhanced individual (Sigma, Laves, Mu, B2).
