Chemical medium-range order in a medium-entropy alloy [PDF]
Nature Communications, 2022 The existence of chemical medium-range order (CMRO) in high- and medium- entropy alloys remains conjectural. Here the authors show evidences of CMRO by electron diffraction spots of lattice periodicity, observable entities, occupancy of preferential ...

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

Magnetocaloric Effect in ScGdHo Medium-entropy Alloy [PDF]
Journal of Superconductivity and Novel Magnetism, 2022 Abstract The search for effective solid-state refrigerant for magnetocaloric application is one of the main-stream topics in materials science. Rareearth multi-principal element alloys seem to be promising candidates for these purposes. In this study, we address the issues of structure formation, magnetic and magnetocaloric properties in ScGdHo ...

Superior Strength-Ductility Cocrni Medium-Entropy Alloy Wire [PDF]
SSRN Electronic Journal, 2020 Abstract High strength-ductility is the prerequisite requirement for the widely used steel wires in engineering applications. Traditional strengthening strategies on these wires are suffocated inevitably by strength-ductility trade-off dilemma. Recent emerging medium-entropy alloys (MEAs) usually exhibits excellent ductility but relatively lower ...
