“…The structural intricacy of HEAs plays a fundamental role in their unique attributes, including solid-solution strengthening, improved conductivities (both thermal and electronic), and enhanced irradiation resistance [66][67][68][69]. These properties are a consequence of the variability in lattice distortion, which varies with composition and crystallographic structure.…”

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.

Erythritol‐based nanocapsules with a phase‐change temperature of 120 °C are successfully prepared under very mild conditions. The nanocapsules are produced via multiple crystallization precipitations from a saturated erythritol aqueous solution, followed by SiO2 coating using a sol–gel method. Their nanostructure and elemental composition are characterized using scanning electron microscopy and energy‐dispersive X‐ray spectroscopy. The latent heat of the nanocapsules is measured with a differential scanning calorimeter. The erythritol nanocapsules, with an average size of ≈220 nm, exhibit a melting enthalpy of 192.7 J g−1. Notably, the supercooling degree of the nanocapsules is reduced by ≈30.0 °C compared to pure erythritol. After 200 thermal cycles, the heat storage performance of the nanocapsules shows only a 7.6% decrease. A latent heat functional thermal fluid, suitable for high‐temperature heat transfer, is prepared by dispersing the nanocapsules in silicone oil. The thermal conductivity and specific heat capacity of this fluid increase by 20.5% and 283.3%, respectively, compared to pure silicone oil. These findings demonstrate that erythritol nanocapsules significantly enhance the thermal properties of high‐temperature heat transfer fluids, highlighting their potential for high‐temperature heat storage and transfer application.
