Abstract：High entropy alloys have been newly developed in recent years, among which the refractory high
entropy alloys obtain excellent high-temperature mechanical properties, thus showing great potential application as
structural materials at ultra-high temperatures. However, their low oxidation resistance at high temperatures limits
the practical engineering applications. The conventional way to enhance oxidation resistance is alloying elements
such as Al, Cr, Si and so on, but the additional amount is usually restricted by other factors, which greatly limits
the oxidation resistance performance. The multi-component characteristics of high-entropy alloys allow them to be
more likely to alloy more oxidation resistance-promoting elements. In this paper, the recent progress in improving
the oxidation resistance of high-entropy alloys was reviewed. The approaches to improve the oxidation resistance
of refractory high-entropy alloys were prospected via adding Al, Cr and Si elements and the formation of
antioxidant coatings.
