A Promising New Class of High-Temperature Alloys: Eutectic High-Entropy Alloys [PDF]

Scientific Reports, 2014
High-entropy alloys (HEAs) can have either high strength or high ductility, and a simultaneous achievement of both still constitutes a tough challenge. The inferior castability and compositional segregation of HEAs are also obstacles for their technological applications.

A new complex-regular eutectic in the Fe7(CoNiMn)93-xBx high entropy alloys

Journal of Materials Research and Technology
Phase constituents and solidification microstructures of as-cast Fe7(CoNiMn)93-xBx (x = 9, 13) HEAs were investigated via electron backscattered diffraction and transmission electron microscopy. It was observed that the phase constituents contain an FCC1

Overcoming strength-toughness trade-off in a eutectic high entropy alloy by optimizing chemical and microstructural heterogeneities

Communications Materials
The well-known strength-toughness trade-off has long been an obstacle in the pursuit of advanced structural alloys. Here, we develop a eutectic high entropy alloy that effectively overcomes this limitation.

A eutectic high-entropy alloy with good high-temperature strength-plasticity balance

Materials Research Letters, 2019
We developed a eutectic high-entropy alloy (EHEA) with appreciable high-temperature strength-plasticity balance. Structural characterizations of the as-cast sample revealed a lamellar structure with austenite (face-centered-cubic, FCC) and Laves phases ...

Corrosion of Eutectic High-Entropy Alloys: A Review

Crystals, 2023
High-entropy alloys (HEAs) are emerging as a new family of alloys with equal/near-equal amounts of constituting elements and outstanding properties. In particular, eutectic high-entropy alloys (EHEAs) with alternate lamella phases possess both high strength and ductility, offering the advantage of conquering the strength–ductility trade-off that could ...
