A crucial review on recent updates of oxidation behavior in high entropy alloys

摘要

Recently, High entropy alloys (HEAs) advanced into high-temperature applications as potential candidates by enduringhigh temperatures with high thermal stability, higher oxidation and corrosion resistances, thermal fatigue, and creepresistances. HEAs acquire unique characteristics called core effects of HEAs: high entropy effect, sluggish diffusion effect,severe lattice distortion, and cocktail effect. HEAs frequently exhibit remarkable properties because of having such uniquecore effects. Thus, the emergence of HEAs has gained significant interest in the field of materials leading to a contemporarypoint of discussion on their exciting nature and properties. The current review article intends to summarize thesignificant works on the oxidation behavior of High entropy alloys (HEAs). Also, peculiar attention has been invested incomprehending oxidation behavior of HEAs in the viewpoint of the crystal structure that is BCC-HEAs, FCC-HEAs andfew case studies were compared with the conventional alloys. Current challenges and essential future directions in thisfield are also pointed out.
