Recent Progress with BCC-Structured High-Entropy Alloys

Metals, 2022
High-entropy alloys (HEAs) prefer to form single-phase solid solutions (body-centered cubic (BCC), face-centered cubic (FCC), or hexagonal closed-packed (HCP)) due to their high mixing entropy.

A perspective on precipitation-hardening high-entropy alloys fabricated by additive manufacturing

Materials & Design, 2021
The growing demand for advanced metallic materials with optimum mechanical properties has led to the creation of next-generation materials based on the alloying of multiple-principal elements in high concentrations. High-entropy alloys (HEAs) have a high

Direct Measure of Giant Magnetocaloric Entropy Contributions in Ni-Mn-In [PDF]

, 2016
Off-stoichiometric alloys based on Ni 2 MnIn have drawn attention due to the coupled first order magnetic and structural transformations, and the large magnetocaloric entropy associated with the transformations. Here we describe calorimetric and magnetic

Hexagonal High-Entropy Alloys

, 2014
We report on the discovery of a high-entropy alloy with a hexagonal crystal structure. Equiatomic samples in the alloy system Ho-Dy-Y-Gd-Tb were found to solidify as homogeneous single-phase high-entropy alloys.
