Thermodynamic Investigations on the Component Dependences of High-entropy Alloys

Abstract—In the present research, a study on the thermodynamical properties of the quinary Co–Cu–Cr–
Fe–Ni high-entropy alloys and ternary Ca–Sb–Yb is carried out by the models Kohler, Chou’s general solution
method (GSM) and Muggianu. The dependences of composition variation on thermodynamic properties,
such as enthalpy of mixing of Co–Cu–Cr–Fe–Ni alloys in simple FCC phase are investigated at the
temperatures 1273, 1373, and 1473 K. Moreover, a comparison between the results of the three models and
those of other theoretical models shows good mutual agreement.
