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.

High-entropy alloy: challenges and prospects
TL;DR: In this paper, a critical review of the recent studies aiming to address the fundamental issues related to phase formation in high-entropy alloys is provided, and novel properties of HEAs are also discussed, such as their excellent specific strength, superior mechanical performance at high temperatures, exceptional ductility and fracture toughness at cryogenic temperatures, superparamagnetism and superconductivity.

Junyang He,Hao Wang,He Huang,Xiandong Xu,Mingwei Chen,Yuan Wu,Xiongjun Liu,T.G. Nieh,Ke An,Zhaoping Lu +9 more
TL;DR: In this paper, the authors demonstrate the possibility to precipitate a coherent reinforcing phase in a fcc-FeCoNiCr HEA matrix using minor additions of Ti and Al, and demonstrate that extraordinary balanced tensile properties at room temperature were achieved, which was due to a well combination of various hardening mechanisms, particularly precipitation hardening.
