AlCrFeNiCu high-entropy alloy (THA) was synthesized by the arc melting and casting method. The alloy exhibits simple FCC and BCC solid solution phases rather than intermetallic compounds. The reason is that the Gibbs free energy of mixing of the equimolar AlCrFeNiCu alloy is smaller than that of inter-metallic compounds by calculation according to the Miedema model.
