摘要
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.
