Seaweed eutectic-dendritic solidification pattern in a CoCrFeNiMnPd eutectic high-entropy alloy

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: A low-cost Co-free eutectic high entropy alloy (EHEA) system was designed, successfully prepared and characterized in this article, which showed excellent mechanical properties with an ultimate strength of 1357 MPa and a total elongation of 6.4% at the cast condition.

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, a simple and practicable pseudo binary method was proposed to design EHEAs using the parameters of valence electron concentration (VEC) and mixing enthalpy (Hmix).

TL;DR: In this paper, it was shown that the confusion principle does not apply, and other factors are more important in promoting glass formation of late transition metal rich multicomponent alloys.

TL;DR: The concept of high entropy introduces a new path of developing advanced materials with unique properties, which cannot be achieved by the conventional micro-alloying approach based on only one dominant element as mentioned in this paper.

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.

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.
