“…In a different research, Liu et al [ 42 ] investigated the effect of Ti on the microstructure and oxidation of (CoNiFe) 60 Al 15 Cr 25− x Ti x ( x = 5–10 at%) alloys at 900 °C for 25–100 h. The (CoNiFe) 60 Al 15 Cr 25− x Ti x alloys exhibited dendritic and interdendritic structures comprising a mixture of FCC and BCC phases, ordered and disordered. The results showed that H6T‐5 mainly comprised of Cr 2 O 3 and Al 2 O 3 , with an inner Al 2 O 3 scale developed below the outer Cr 2 O 3 scale.…”

This article reviews the oxidation behaviour of the two most significant high entropy alloy systems (HEAs) namely Cantor‐based and refractory HEAs. HEAs have been extensively researched and show potential applications in various industries, including marine engine manufacturing, chemical industry, furnaces, ducting, heat exchangers, jet engines, steam turbines, nuclear reactors and electronic devices, among others. Effect of the presence of elements such as aluminium, manganese, chromium, silicon, tantalum, vanadium etc. are studied for catalysing the oxidation of HEAs. Aluminium, chromium and silicon are reportedly found to considerably impact the oxidation kinetics and enhance the oxidation resistance. However, silicon can positively or adversely affect the oxidation resistance depending on its concentration and alloy composition. Other elements like manganese tend to adversely impact the oxidation resistance of FeCoNi‐based HEAs. Refractory elements are typically found to be not suitable for oxidation studies due to the formation of non‐protective oxide layers. However, refractory HEAs offer interesting trends both in terms of enhancing or reducing oxidation resistance depending on the alloying elements. Similarly, findings related to other elements are also presented and elaborated.This article is protected by copyright. All rights reserved.

“…The inherent properties of HEAs provide them with many unparalleled excellent properties compared to conventional alloys, such as high-temperature resistance, friction resistance, oxidation resistance, corrosion resistance and strong hardness [8][9][10][11], which have attracted extensive interest from material researchers. At the same time, the cocktail effect of HEAs also allows researchers to modulate the alloy properties through appropriate composition design [12][13][14].…”

In this study, CoCrFeNiAl0.1-RE HEA was melted using a magnetic levitation melting furnace, resulting in a single-phase FCC solid solution structure with a coarse irregular equiaxed grain morphology in the period. The oxidation experiment results showed that the samples’ oxidation kinetics followed the parabolic rate law, and the oxidation product species increased with increasing temperature. High temperatures primarily revealed Cr2O3, (Cr, Fe)2O3, and other spinel phases such as NiFe2O4, CoCr2O4, and CoFe2O4. Under the oxide film, Al-rich striped raised phases were observed. According to the elemental divisions, the oxide film will be damaged to expose the FCC matrix in molten salt corrosion, and the film can be divided into four layers: peeling layer, newly oxidised-corroded outer layer, transition layer, and matrix. As molten salt is destroyed, cavities and channels appear in the film, allowing molten salt and oxygen to infiltrate and accelerate the oxidation and corrosion of the sample.
