Abstract. High-entropy alloys (HEAs) are advanced materials composed of multiple principal elements in near-equiatomic ratios. Specialized HEAs display exceptional performance in high-temperature strength, oxidation resistance, and creep resistance, making them viable for aerospace and nuclear applications. Biomedical HEAs have emerged with promising corrosion resistance, biocompatibility, and mechanical properties suitable for implants. Despite significant progress in optimizing alloy characteristics, challenges remain regarding cost, accurate phase prediction, and scalable manufacturing. Future advancements are expected through interdisciplinary strategies incorporating advanced modelling, machine learning, and additive manufacturing.
Keywords: High-Entropy Alloys (HEAs); multicomponent systems; mechanical properties; corrosion resistance; biomedical alloys
