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.

Bernd Gludovatz,Anton Hohenwarter,Dhiraj Catoor,Edwin H. Chang,Easo P. George,Easo P. George,Robert O. Ritchie,Robert O. Ritchie +7 more
TL;DR: This work examined a five-element high-entropy alloy, CrMnFeCoNi, which forms a single-phase face-centered cubic solid solution, and found it to have exceptional damage tolerance with tensile strengths above 1 GPa and fracture toughness values exceeding 200 MPa·m1/2.

Metastable high-entropy dual-phase alloys overcome the strength–ductility trade-off
TL;DR: In this metastability-engineering strategy, a transformation-induced plasticity-assisted, dual-phase high-entropy alloy (TRIP-DP-HEA) is designed, which combines the best of two worlds: extensive hardening due to the decreased phase stability known from advanced steels and massive solid-solution strengthening of high-ENTropy alloys.
