Figure 9. Nyquist (A) and Bode plots (B) of the CrxMnFeCoNi (x = 0, 0.6, 1, and 1.5) HEAs in a 0.5 M H2SO4 solution under open circuit potential condition. The inset in (A) is the electrical equivalent circuit (EEC) for fitting the EIS results. HEAs: High-entropy alloys; EIS: electrochemical impendence spectroscope.
