Beschreibung
This high-entropy alloy (HEA) with nominal composition Co0.043 Nb0.638 Ni1 Ta0.255 Ti0.191 is a predominantly face-centered cubic (FCC) austenitic alloy system within the multi-principal element alloy research space, incorporating Co, Nb, Ni and 2 additional elements. Key properties include tunable mechanical properties through compositional adjustment, with combined solid-solution and precipitation strengthening mechanisms; titanium additions promote intermetallic precipitation for additional strengthening. Investigated applications include alloy design research, structural coatings, and specialized functional applications.
