Influence of the Cr to Ti Ratio on the High‐Temperature Oxidation Behavior of TaMoCrTiAl Complex Concentrated Alloys in Nitrogen‐Free Atmospheres

open access: yesMaterials and Corrosion, Volume 77, Issue 3, Page 442-452, March 2026.
Ta‐Mo‐Cr‐Ti‐Al refractory high‐entropy alloys show atmosphere‐dependent oxidation performance based on Cr:Ti ratios. Cr‐rich compositions excel in dry oxygen through continuous chromia formation, while Ti‐rich alloys perform better in humid conditions due to reduced chromium volatilization and hydrogen uptake effects.
