Description
This high-entropy alloy (HEA) with nominal composition Al1 Cu0.889 Fe0.667 Ni0.889 Ti1 is a predominantly face-centered cubic (FCC) austenitic alloy system within the multi-principal element alloy research space, incorporating Al, Cu, Fe and 2 additional elements. Key properties include exceptional room-temperature ductility, high work hardening rate, and good corrosion resistance in aggressive media; titanium additions promote intermetallic precipitation for additional strengthening. Investigated applications include structural components, wear-resistant coatings, and cryogenic applications.
