Owing to attractive engineering properties , high entropy alloys ( HEAs ) have drawn great attention over the past decade . During this time of exploration , most studies have been focused on one of the original concepts of HEAs for alloy design , which utilizes an equiatomic ratio of multiple principal elements to obtain the maximum configurational entropy [ 1 ] . However , this design concept limits the compositional space and excludes non - equiatomic candidates with potentially outstanding properties and more commercially viable . The concept of non - equiatomic HEAs , first put forward by Raabe and his colleagues [ 6 - 10 ] , has greatly expanded the compositional space for hea design , and work on these compositions has achieved unparalleled mechanical properties [ 6 ] . On the other hand , in the development of traditional metals and alloys , modification of mechanical properties through controlled microstructure design has succeeded in many studies . Heterogeneous lamella structures , bimodal structur
