A critical review of high entropy alloys and related concepts
Daniel B. Miracle,Oleg N. Senkov +1 more
TL;DR: High entropy alloys (HEAs) are barely 12 years old as discussed by the authors, and the field has stimulated new ideas and inspired the exploration of the vast composition space offered by multi-principal element alloys.

Zhifeng Lei,Xiongjun Liu,Yuan Wu,Hui Wang,Suihe Jiang,S. D. Wang,Xidong Hui,Yidong Wu,Baptiste Gault,Paraskevas Kontis,Dierk Raabe,Lin Gu,Qinghua Zhang,Houwen Chen,Hongtao Wang,Jiabin Liu,Ke An,Qiaoshi Zeng,T.G. Nieh,Zhaoping Lu +19 more
TL;DR: It is shown that oxygen can take the form of ordered oxygen complexes, a state in between oxide particles and frequently occurring random interstitials, which lead to unprecedented enhancement in both strength and ductility in compositionally complex solid solutions, the so-called high-entropy alloys (HEAs).
Journal ArticleDOI
Development and exploration of refractory high entropy alloys—A review
