Magnesium Containing High Entropy Alloys

, 2022
High Entropy alloys (HEAs) or Complex Concentrated Alloys (CCAs) or Multi-Principal Element Alloys (MPEAs) is a matter of interest to material scientists for the last two decades due to the excellent mechanical properties, oxidation and corrosion resistant behaviors. One of the major drawbacks of HEAs is their high density.

Achieving synergistic strength-ductility enhancement in a hierarchical hetero-lamellar AlCoCrFeNi2.1 eutectic high-entropy alloy via facile hot-rolling strategy

Materials & Design
Eutectic high-entropy alloys (EHEAs) have attracted considerable interest due to their superior multifunctional performance. However, the inherent tendency of stress concentration at irregular phase boundaries frequently leads to premature fracture. This

Progress in High-Entropy Alloys [PDF]

JOM, 2013
Strictly speaking, high-entropy alloys (HEAs) refer to single-phase, solid-solution alloys with multiprincipal elements in an equal or a near-equal molar ratio whose configurational entropy is tremendously high. This special topic was organized to reflect the focus and diversity of HEA research topics in the community.
