Thermodynamic investigations on the component dependences of high-entropy alloys

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.
