説明
This high-entropy alloy (HEA) with nominal composition Mo1 Nb1 Si0.5 Ta1 W1 is a predominantly face-centered cubic (FCC) austenitic alloy system within the multi-principal element alloy research space, incorporating Mo, Nb, Si and 2 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. Investigated applications include high-temperature structural applications, advanced gas turbine components, nuclear energy systems, and refractory coating materials.
