| Abstract Scope |
The niobium-titanium (Nb-Ti) system offers high-temperature stability and potential spinodal strengthening, however limited data exists on its sprayability and phase evolution. The ability to tailor AM processing for refractory alloys to design robust high-performance components for aerospace and nuclear applications is the motivation for this work. This work investigates cold spray additive manufacturing of Nb-Ti alloys across a range of compositions to evaluate process-structure-property relationships in the Nb-rich region of the alloy system. The aim is to improve post-deposition strength without sacrificing toughness by leveraging multiple powder processing strategies–including ultrasonic atomization of pre-alloyed feedstocks, mechanical alloying of elemental blends, and electroless-plated core-shell structures. Microstructural evolution, diffusion behavior, and potential spinodal strengthening during post-cold spray heat treatments across Nb contents ranging from 50-95 at% will be presented and discussed. |
