Abstract
Oxidation behavior of Al8Cr13.3Fe63.5Ni11.2Ti4 complex concentrated alloy was studied in the air at 800 °C. Results show that the oxidation kinetics does not obey a parabola relationship. The oxidation process was divided into two distinct stages, transforming from an approximately parabolic law to a quasi-linear law at 10 h. This alloy exhibits excellent oxidation resistance with only 0.41 mg/cm2 of specific mass gain after 100 h oxidation, ascribed to the compact outer CrTi2O5 +TiO2 and inner Cr2O3 +nano-scale CrTi2O5 oxide layers. However, this oxide scale does not prevent the N from diffusion inward, forming the TiN and AlN in internal oxidation zone. © 2023 Elsevier Ltd.
