TL;DR: Eutectic high-entropy alloys (EHEAs) are becoming a new research hotspot in the metallic materials community because of their excellent castability, fine and uniform microstructures even in the as-cast state, high strength, and good ductility as discussed by the authors.

TL;DR: In this article, a mixing enthalpy-based strategy was used to locate eutectic compositions in high entropy alloys (EHEAs) and a series of EHEAs were located and prepared following the mixing entropy method.

TL;DR: In this paper, a simple and effective strategy by combining mixing enthalpy and constituent binary eutectic compositions was proposed to design EHEA compositions, which was then applied to a series of (CoCrFeNi)Mx (M = Nb, Ta, Zr, Hf) HEAs, leading to the discovery of new EHEAs.

TL;DR: In this paper, the authors investigated the alloying effects of Ta on microstructures and mechanical properties of CoCrFeNiTax high entropy alloys and showed that the effect of Ta element on microstructure changes from an initial single FCC solid solution (x = 0) to a hypoeutectic micro-structure (x= 1) and then to a fully eutective micro-structured (x ≥ 0) with a mixture of FCC and Co2Ta-type Laves phases.

TL;DR: In this article, the effects of Mo and W elements on the microstructures and mechanical properties of the alloys were investigated, and results showed that by decreasing the Mo andW contents to 0.8 in Co2MoxNi2VWx alloy, a fully eutectic microstructure was obtained.
