Beschreibung
This complex concentrated alloy (CCA) with nominal composition C0.429 Co1 Cr1 Fe1 Ni1 W0.429 is a predominantly face-centered cubic (FCC) austenitic alloy system within the multi-principal element alloy research space, incorporating C, Co, Cr and 3 additional elements. Key properties include good strength-ductility balance, high fracture toughness especially at cryogenic temperatures, and moderate corrosion resistance; molybdenum/tungsten additions provide enhanced solid-solution strengthening and creep resistance; carbon additions form MC-type carbides that strengthen grain boundaries. Investigated applications include cryogenic structural components, alloy design research platforms, and high-entropy coating systems.
