Nanostructured High-Entropy Alloys with Multiple Principal Elements: Novel Alloy Design Concepts and Outcomes
Abstract: A new approach for the design of alloys is presented in this study. These high-entropy alloys with multi-principal elements were synthesized using well-developed processing technologies. Preliminary results demonstrate examples of the alloys with simple crystal structures, nanostructures, and promising mechanical properties. This approach may be opening a new era in materials science and engineering.

...One of the earliest papers defines HEAs as, “those composed of five or more principal elements in equimolar ratios” ....
...Diffusion is proposed to be sluggish in HEAs [6,21]....
...Given that commonly studied HEAs have extended SS phase fields (Section 18.104.22.168) and that IM phases often have restricted composition ranges, single-phase IM alloys are expected to be relatively uncommon (Section 2.3.1)....
...Several thermodynamic models have been used to estimate the phases in HEAs....
...Some papers introduce HEAs as equimolar alloys only and some use different values of SSS,ideal to specify HEAs....
