| 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. Improvements in single and polycrystalline R-MPEA growth and other novel alloy developments holds great promise, but the current scarcity of ultrahigh temperature tensile and creep experiments is a serious impediment. Recognizing the benefits associated with rapid characterization, a milli-scale high-throughput instrument has been developed to obtain the tensile and creep properties of ultrahigh temperature materials in high-vacuum and over a range of temperatures. Experiments involving a first-generation Senkov alloy, HfNbTaTiZr, will be used to demonstrate the efficacy of this new methodology. Results for a number of milli-scale refractory metals and alloys will be shared and used to elucidate the processing-structure-property relations that underpin their ultrahigh temperature mechanical behavior. |
