| Abstract Scope |
Refractory metals find significant use in aerospace, defense, and nuclear applications where environments are extreme and dynamic. The development of cold spray additive manufacturing processes enables the efficient use of refractory metals as a coating material in these advanced applications where operating temperature, strength, ductility, and wear are critical performance metrics. This research discusses the rapid optimization of heat treatment processes for improving the performance of cold sprayed niobium with a focus on improving the overall toughness of the coating. Heat treatments were performed in a vacuum atmosphere, and tension tests were conducted using a miniaturized sample proportional to the ASTM E8 standard. Hardness, microstructure, and tensile behavior provide a preliminary assessment of performance in extreme environments. |
