Microstructure and properties of laser re-melting FeCoCrNiAl0.5Six high-entropy alloy coatings
TL;DR: In this article, high-entropy alloy (HEA) was synthesized with premixed high-purity Fe, Co, Cr, Ni, Al and Si powder on Q235 steel by using atmospheric plasma spraying and laser re-melting surface alloying, aiming to investigate the effects of different Si molar concentrations on the phase constituents, microstructure evolution, microhardness and properties of HEA coatings.

Design of High-Entropy Alloy: A Perspective from Nonideal Mixing
TL;DR: In this article, the authors discuss the design of high-entropy alloys from the perspective of correlated mixing and show that the formation of a random solid solution in HEAs depends not only on the number of constituent elements but also on the alloy's melting/processing temperature and on various interatomic correlations.
