The Gibbs free energy of liquid and crystal, intermetallic compounds, and amorphous phases were investigated by thermodynamic analysis for microstructure of high-entropy alloy (HEA). Results show that the value of Delta S-r Delta H-h(sol.) plays an important role in estimating the microstructure of HEAs. The alloys with lower value of Delta S-r Delta H-h(sol.) have stronger tendency of forming single fcc or bcc solid solution, and the alloy with complicated microstructure always has larger value of Delta S-r Delta H-h(sol.).
