Abstract
The oxidation behavior of MoNbVTa0.5Crx (x = 0.25–1) refractory high entropy alloys (RHEAs) at 800 ℃ was studied. The oxidation resistance of the alloy significantly increased with the increase of Cr content. Due to the formation of dense CrNbO4/CrTaO4 oxide layers, MoNbVTa0.5Cr alloy exhibited promising oxidation resistance, with a specific mass gain of 47.76 mg/cm2 after 36 h of oxidation in air at 1100 ℃. The oxidation kinetics of MoNbVTa0.5Cr alloy at 800–1100 ℃ conformed to parabolic kinetics, and the internal oxidation of alloys was mainly caused by the inward diffusion of oxygen. This study provides valuable reference for the development of antioxidant RHEAs.
