Advanced high-entropy alloys breaking the property limits of current materials

The growing need for stronger and more ductile structural materials has spurred an intense search for innovative, high-performance alloys. Traditionally, alloys face a pervasive trade-off: high strength often comes at the expense of ductility and vice versa. The advent of high -entropy alloys (HEAs) offering both high strength and ductility has transformed this landscape. In this work, we discuss the deformation mechanisms of HEAs, examine the foundations of the strength -ductility trade-off, and explore approaches for designing HEAs to surmount this limitation. Furthermore, we analyze the factors that govern HEA-deformation performance, which in turn influence the HEA design. We also propose a perspective on future research directions concerning the mechanical behavior of HEAs, highlighting potential breakthroughs and novel strategies to advance the field.
