Abstract

To better understand the corrosion behaviors of CoCrFeNi-based high-entropy alloys (HEAs), the CALculation of PHAse Diagrams (CALPHAD) method was used to simulate the Pourbaix diagrams for CoCrFeNi, CoCrFeNiCu and CoCrFeNiAl HEAs. Although the CALPHAD simulations were performed under equilibrium conditions, assisted by published experimental results on CoCrFeNi, CoCrFeNiCu and CoCrFeNiAl_0.5 HEAs, the CALPHAD simulations provide insights into the corrosion behaviors, such as the oxidation layer pitting and forming potential, of the CoCrFeNi-based HEAs.
