Beschreibung
This medium-entropy alloy (MEA) with nominal composition Co1 Cr1 Cu1 Fe1 is a predominantly face-centered cubic (FCC) austenitic alloy system within the multi-principal element alloy research space, incorporating cobalt, chromium, copper, and iron. Key properties include good strength-ductility balance, high fracture toughness especially at cryogenic temperatures, and moderate corrosion resistance. Investigated applications include cryogenic structural components, alloy design research platforms, and high-entropy coating systems.
