Stacking Fault Driven Phase Transformation in CrCoNi Medium Entropy Alloy [PDF]
Nano Letters, 2021 Phase transformation is an effective means to increase the ductility of a material. However, even for a commonly observed face-centered-cubic to hexagonal-close-packed (fcc-to-hcp) phase transformation, the underlying mechanisms are far from being settled.

Electrodeposition of a CoNiCu medium-entropy alloy in a water-in-oil emulsion
Electrochemistry Communications, 2021 A medium-entropy alloy (MEA) of CoNiCu with a face-centered cubic structure was successfully obtained by electrochemical deposition. To achieve a nearly equiatomic composition, a water-in-oil emulsion was used as the solution for electrodeposition. Since

Tensile properties of high- and medium-entropy alloys [PDF]
Intermetallics, 2013 Abstract Equiatomic, face-centered-cubic, high- and medium-entropy alloys were arc melted, hot-rolled to produce recrystallized sheets, and tensile tested. The alloys having the compositions CrMnFeCoNi and CrFeCoNi exhibited a strong temperature-dependent decrease in strength with increasing temperature from −196 °C to 1000 °C, and a relatively weak ...
