High-Entropy Alloys (HEAs) [PDF]
Metals, 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[...]

The Surface Properties of Implant Materials by Deposition of High-Entropy Alloys (HEAs)
Nanomaterials, 2023 High-entropy alloys (HEAs) contain more than five alloying elements in a composition range of 5–35% and with slight atomic size variation. Recent narrative studies on HEA thin films and their synthesis through deposition techniques such as sputtering have highlighted the need for determining the corrosion behaviors of such alloys used as biomaterials ...

Development of eutectic high entropy alloy by addition of W to CoCrFeNi HEA
International Journal of Refractory Metals and Hard Materials, 2023 High entropy alloys have shown a remarkable combination of physical and mechanical properties. The introduction of eutectic microstructure, consisting of a tough fcc phase, and a hard-intermetallic phase, can help in obtaining even better synergy of strength and ductility.

Effective and back stresses evolution upon cycling a high-entropy alloy
Materials Research Letters, 2022 We report on the effective and back stresses evolution of a CoCrFeMnNi high-entropy alloy (HEA) by partitioning its cyclic hysteresis loops. It was found that the cyclic stress response of the HEA predominantly originates from the back stress evolution ...
