“…They combine exceptional mechanical properties like high tensile strength, flexibility, and hardness, making them suitable for various nuclear applications, including reactor pressure vessels and fuel cladding. HEAs maintain structural integrity under extreme temperatures and show excellent resistance to creep, making them ideal for high-temperature nuclear reactor environments [83][84][85]. Additionally, HEAs offer superior resistance to radiation-induced damage compared to conventional alloys, due to their unique atomic structures and high configurational entropy, enhancing their long-term durability in nuclear reactors [86,87].…”

High-entropy alloys (HEAs) are advanced materials characterized by their unique and complex compositions. Characterized by a mixture of five or more elements in roughly equal atomic ratios, these alloys diverge from traditional alloy formulations that typically focus on one or two principal elements. This innovation has paved the way for subsequent studies that have expanded our understanding of HEAs, highlighting the role of high mixing entropy in stabilizing fewer phases than expected by traditional phase prediction methods like Gibbs’s rule. In this review article, we trace the evolution of HEAs, discussing their synthesis, stability, and the influence of crystallographic structures on their properties. Additionally, we highlight the strength–ductility trade-off in HEAs and explore strategies to overcome this challenge. Moreover, we examine the diverse applications of HEAs in extreme conditions and their promise for future advancements in materials science.
