Research Status and Prospect of High Entropy Alloy Compound Films [PDF]

Cailiao Baohu, 2022
High entropy alloy compound film is a two-dimensional material prepared based on the design idea of multi-principal element high entropy alloys. In addition to its metal elements， non-metallic elements such as C， N and O are added to form strong metal ...

High-entropy alloys

, 2014
This book provides a complete review of the current state of the art in the field of high entropy alloys (HEA). The conventional approach to alloy design is to select one principal element and add elements to it in minor quantities in order to improve ...

Noble metal high entropy alloy for mid infrared metasurfaces [PDF]

, 2023
We have experimentally determined the complex permittivity of a high entropy alloy (HEA) composed of five noble metals: Au, Ag, Cu, Pd, Pt. The permittivity was measured in a wide range of wavelengths from ultraviolet via visible to mid-infrared.

High Entropy Alloys: Ready to Set Sail? [PDF]

Metals, 2020
Over the past decade, high entropy alloys (HEAs) have transcended the frontiers of material development in terms of their unprecedented structural and functional properties compared to their counterpart conventional alloys. The possibility to explore a vast compositional space further renders this area of research extremely promising in the near future

Local Order in AgAuCuPdPt High-Entropy Alloy Surfaces [PDF]

, 2022
Synthesis of high-entropy alloys often involves heating precursors to above 1000 °C such that entropy stabilization takes effect. The resulting alloys are characterized by random element distribution at the bulk lattice positions. Surfaces may however be

High entropy alloy nanoparticle formation at low temperatures [PDF]

, 2022
Entropy-driven formation of high entropy alloy (HEA) nanoparticles from metal precursors requires high temperatures and controlled cooling rates. However, several proposed HEA nanoparticle synthesis strategies avoid the high-temperature regime.
