Microstructure and high-temperature oxidation behavior of high entropy Nb-Cr-W-Ta-V alloy has been explored in this study. High temperature oxidation studies in the temperature range of 600-1400oC indicated interesting phase evolution in the alloy. The chemical composition and microstructure analysis of the oxide layer was analyzed in order to understand the mechanism involved in the oxidation process. The V-oxide appears in a perfectly whisker morphology while other oxides appear in crystalline forms with either granular, more or less, or tube/cylindrical morphologies. A more detailed account of the microstructure and oxidation behavior of the Nb-Cr-W-Ta-V alloy will be presented.
