Abstract Scope |
Refractory alloys, including refractory multi-principal element alloys (R-MPEAs), have immense potential for use at ultrahigh temperatures and in extreme environments required for energy-efficient power generation, hypersonic flight, and space access. Advancements in the alloy design of single and multi-phase R-MPEAs hold great promise, but the current scarcity of ultrahigh temperature tensile and creep experiments remains a serious impediment. Two recent studies have provided tensile data up to 1200°C, but tensile studies at R-MPEA target use temperatures have not been published. Recognizing the benefits associated with rapid characterization, a sub-scale high-throughput instrument has been developed to obtain the tensile and creep properties of ultrahigh temperature materials in high-vacuum and up to 2000°C. Experiments involving a range of R-MPEA alloys will be presented used to elucidate the processing-structure-property relations that underpin their ultrahigh temperature mechanical behavior. |
