설명
This medium-entropy alloy (MEA) with nominal composition Cr1 Nb1 Ta1 Ti1 is a predominantly face-centered cubic (FCC) austenitic alloy system within the multi-principal element alloy research space, incorporating chromium, niobium, tantalum, and titanium. Key properties include very high melting point (>1800°C), excellent high-temperature strength retention, and good oxidation resistance at elevated temperatures; 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.
