Abstract
Eutectic high entropy alloys (EHEAs) are recently of great interest due to their excellent mechanical properties. However, only a few EHEAs have so far been designed because of the lack of multi-component phase diagrams. Here, a new Fe20Co20Ni41Al19 EHEA was successfully designed and studied. The alloy exhibited a nano-lamellar eutectic microstructure composed of ordered BCC (B2) phase and ordered FCC (L12) phase. The room-temperature tensile strength and total elongation of the alloy were as high as 1103â¯MPa and 18.7%, respectively, which were better than those of a majority of as-cast high entropy alloys. The new alloy has a potential application in industry and will promote the further study of EHEAs.
