Article Abstract

Eutectic high-entropy alloys (EHEAs) have combined both high-entropy alloys and eutectic alloy contributions, with excellent castability and high-temperature application potential. Yet, multielement/triple-phase eutectic high-entropy alloy (TEHEA) designs remain puzzling. This work proposed a new strategy based on an infinite solid solution and pseudo-ternary model to reveal the puzzle of TEHEAs. The designed triple-phase eutectic high-entropy alloys (TEHEAs) with more than seven elements were identified as face-centered cubic (FCC), ordered body-centered cubic (B2), and Laves phase structures. In this work, the alloy C showcases outstanding comprehensive mechanical properties, offering a novel avenue for the design of high-performance EHEAs.

High-entropy doping of multicomponent alloy nanocrystals enclosed by high-index facets (HIFs) is a great challenge due to the high surface energy from HIFs and their distinct standard reduction potential and atom sizes between different metals. Herein, a novel non-aqueous system, choline chloride-urea-based deep eutectic solvent, is proposed as a versatile medium to design a high-entropy rare-earth-doped Pt alloy PtYLaNdSmEuGdTbDyHoEr (HERED-Pt) concave nanocube with HIFs by the electrochemical method. Thanks to the high-index faceted characteristics and the high-entropy rare-earth-doped elemental synergy, the as-synthesized HERED-Pt concave nanocubes exhibit remarkable electrocatalytic performance for hydrazine oxidation reaction (HzOR) with high current density (170.

We report on a pressure induced irreversible phase transformation in an ordered eutectic high-entropy alloy (EHEA) AlCoCrFeNi. The suction cast sample was synthesized by arc melting of raw elements resulting in an ordered B2 and FCC phase mixture for eutectic AlCoCrFeNi alloy. This phase mixture was confirmed by transmission electron microscopy (TEM) where superlattice reflections corresponding to ordered B2 phase were observed while the FCC phase remains disordered.

Eutectic alloys have driven technological advancements for centuries, from early bronze tools that marked the dawn of metallurgy to high-performance soldering materials. Building on this legacy, eutectic high-entropy alloys (EHEAs) have recently emerged to push the boundaries of mechanical performance. However, the strength potential of EHEAs remains largely untapped, primarily because of limitations in cooling rates, posing a significant challenge to the development of ultra-strong bulk EHEAs.
