High-Entropy Alloys [PDF]

open access: yesAdvances in Materials Science and Engineering, 2015
Most metallic alloys contain small concentrations of solutes because they are sufficient to achieve amazing properties on a grand scale of production and utilisation. In the early 1980s, a different concept was introduced that involved mixing large concentrations of solutes in roughly equal amounts so that there is no predominant solvent.

Hexagonal High-Entropy Alloys

open access: yesMaterials Research Letters, 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.

High-Entropy Alloys (HEAs) [PDF]

open access: yesMetals, 2018
High-entropy alloys (HEAs) [1,2] loosely refer to multi-principal-element solid solution alloys due to their high configurational entropy, in contrast to traditional alloys, which focus on the edge or corner of phase diagrams with one principal component[
