Theory-guided design of high-entropy alloys with enhanced strength-ductility synergy [PDF]
Nature Communications, 2023 Metallic alloys have played essential roles in human civilization due to their balanced strength and ductility. Metastable phases and twins have been introduced to overcome the strength-ductility tradeoff in face-centered cubic (FCC) high-entropy alloys (

Tailoring heterogeneities in high-entropy alloys to promote strength–ductility synergy [PDF]
Nature Communications, 2019 Conventional alloys are usually based on a single host metal. Recent high-entropy alloys (HEAs), in contrast, employ multiple principal elements. The strength of HEAs is considerably higher than traditional solid solutions, as the many constituents lead ...

Journal of Materials Research and Technology, 2023 Conventional Mg-RE-based alloys containing a high content of RE solutes can generate high strength, but there is often low ductility. Herein, we reported a low RE alloying Mg–5Er-1Nd-1Zn-0.2Zr extrusion alloy with only 6 wt% RE addition, showing a high ...
