Description
This high-entropy alloy (HEA) with nominal composition Co1 Cr0.667 Fe0.667 Ni1 Ti0.333 is a predominantly face-centered cubic (FCC) austenitic alloy system within the multi-principal element alloy research space, incorporating Co, Cr, Fe and 2 additional elements. Key properties include good strength-ductility balance, high fracture toughness especially at cryogenic temperatures, and moderate corrosion resistance; titanium additions promote intermetallic precipitation for additional strengthening. Investigated applications include cryogenic structural components, alloy design research platforms, and high-entropy coating systems.
