The present invention provides a novel high-entropy alloy and, specifically, provides a high-entropy alloy comprising a body-centric cubic crystal structure, wherein the body-centric cubic crystal structure comprises, as main elements, Al, Ti, and one or more elements selected from Cr, Mo, V,...
Heat treatment technology in high-entropy alloys has also been widely used [19–21]. The microstructure of the AlCoCrFeNiTi0.8 high-entropy alloy had no obvious change after heat treatment at 700 °C. After heat treatment at 1200 °C, the coarsening behavior of the AlNi precipitate was ...
Designing electrocatalysts with high-performance for both reduction and oxidation reactions faces severe challenges. Here, the uniform and ultrasmall (~3.4 nm) high-entropy alloys (HEAs) Pt18Ni26Fe15Co14Cu27nanoparticles are synthesized by a simple low-temperature oil phase strategy at atmospheric ...

High-entropy alloy nanoparticles (HEA-NPs) have promised multi-functional applications ascribing to their unique high-entropy effect, composing elements, and nanoscale size effect. However, how to overcome the immiscibility of all the composing elements and meanwhile downscale them into nanoscale remains...

High-entropy alloys (HEAs) with an atomic arrangement of a hexagonal close-packed (hcp) structure were found in YGdTbDyLu and GdTbDyTmLu alloys as a nearly single hcp phase. The equi-atomic alloy design for HEAs assisted by binary phase diagrams started with selecting constituent elements with...
tionary alloy design concept, namely, high-entropy alloy (HEAs) concept, was proposed and the basic idea is to simultaneously alloy multiple principal elements in equimolar or near equimolar ratios to increase the configuration entropy to stabilize the structures. Since its inception, this new fam...
