Enhanced Oxidation Resistance of AlCoCrFeNi High Entropy Alloy Obtained by Annealing
High-Entropy Alloys (HEAs) have emerged as a promising class of materials for extreme environments due to their unique compositional complexity and the resultant enhanced thermal stability. Among them, AlCoCrFeNi has garnered significant attention for its superior oxidation resistance at elevated temperatures, primarily owing to the formation of protective alpha alumina (Al₂O₃) surface oxide s
