Refractory alloy development enjoyed a golden era in the 1950s–60s, when most known refractory systems were discovered, yielding many alloys still used today. However, progress stalled in subsequent decades as Ni-based superalloys dominated high-temperature applications. This stagnation persisted until 2000s, when the multi-principal element alloys (MPEAs) emerged, renewing interest in exploring novel refractory compositions. In this talk, we present a computational–experimental framework that integrates computational design, rapid synthesis, and high-throughput characterization to accelerate refractory MPEA discovery. It guides alloy the selection of alloys meeting stringent design criteria, a stable BCC phase above 800 °C, a narrow solidification range for castability, and high yield strength. Using vacuum arc melting and homogenization, we rapidly produce and screen candidate alloys with mechanical and thermal property validation to confirm performance and prepare alloy powders for additive manufacturing. This holistic approach shortens development cycles and is relevant for aerospace, energy, and defense applications. |
