Abstract

Oxidation behavior of Al₈Cr_13.3Fe_63.5Ni_11.2Ti₄ 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.
