Abstract

Recently, High entropy alloys (HEAs) advanced into high-temperature applications as potential candidates by enduring high temperatures with high thermal stability, higher oxidation and corrosion resistances, thermal fatigue, and creep resistances. 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 unique core effects. Thus, the emergence of HEAs has gained significant interest in the field of materials leading to a contemporary point of discussion on their exciting nature and properties. The current review article intends to summarize the significant works on the oxidation behavior of High entropy alloys (HEAs). Also, peculiar attention has been invested in comprehending oxidation behavior of HEAs in the viewpoint of the crystal structure that is BCC-HEAs, FCC-HEAs and few case studies were compared with the conventional alloys. Current challenges and essential future directions in this field are also pointed out.
