Ta-W alloys serve as structural alloys for high-temperature and corrosive environments. Renewed interest in refractory alloys for performance in extreme environments, including the development of refractory multi-principal element alloys (RMPEAs), is driving new investigations into the mechanical response of refractory alloys like Ta-W during quasi-static deformation to understand the microstructural response and inform alloy-microstructure-property design. Toward this aim, quasi-static tension testing has been performed at room and elevated temperatures on wrought Ta-10W (wt.%), along with microstructural characterization after deformation. Baselining the microstructure and mechanical response to quasi-static mechanical testing is needed to better understand the deformation mechanisms in Ta-W alloys, and to provide insights into the development of novel RMPEAs for aerospace, defense, and nuclear applications.
