Effect of Co on the phase stability of CrMnFeCoxNi high entropy alloys following long-duration exposures at intermediate temperatures
TL;DR: The effect of Co on the phase stability of the CrMnFeCoxNi family of alloys has been experimentally established following 1000-h heat treatments at 900 and 700°C and up to 5000´h at 500´°C as discussed by the authors.

The intrinsic mechanism of corrosion resistance for FCC high entropy alloys
TL;DR: In this paper, the intrinsic mechanism of corrosion resistance in FCC HEAs was revealed by designing equal atomic alloys with single solid solution phase, which showed that the Cr element played the dominant role in the corrosion resistance rather than the simple structure from high entropy effect or uniform element distribution.
Journal ArticleDOI
A strong, ductile, high-entropy FeCoCrNi alloy with fine grains fabricated via additive manufacturing and a single cold deformation and annealing cycle
TL;DR: In this article, a FeCoCrNi high-entropy alloy fabricated via additive manufacturing (AM) was chosen as the initial material for investigating cold deformation, and the microstructure and mechanical properties of compressed samples (50 % reduction along the building direction) were compared.
