Abstract Scope |
High entropy alloys (HEAs) are primarily used as structural materials and are exposed to oxidizing environments in such applications. This may result in catastrophic failure for the intended purposes. Detailed knowledge in understanding the mechanism of internal oxidation is needed to fine-tune the materials for better performance. We examine the reaction and diffusion process during internal oxidation of a refractory HEA using first principle ab initio methods in combination with atomistic thermodynamic modeling. In addition, we examined the effect of varying metal compositions on the different oxides formed from the alloy at different temperatures. |
