Beschreibung
This complex concentrated alloy (CCA) with nominal composition Cr0.286 Mo0.476 Nb1 Ta0.024 Ti0.31 V0.286 is a predominantly face-centered cubic (FCC) austenitic alloy system within the multi-principal element alloy research space, incorporating Cr, Mo, Nb and 3 additional elements. Key properties include very high melting point (>1800°C), excellent high-temperature strength retention, and good oxidation resistance at elevated temperatures; molybdenum/tungsten additions provide enhanced solid-solution strengthening and creep resistance; titanium additions promote intermetallic precipitation for additional strengthening. Investigated applications include high-temperature structural applications, advanced gas turbine components, nuclear energy systems, and refractory coating materials.
