| Abstract Scope |
The joining of nitinol components by conventional fusion welding techniques has proven a considerable challenge due to the formation of oxides and deleterious intermetallics that occur under high heat. Cold spray welding presents a possible means to circumvent these issues as its solid-state nature permits joining at much lower temperatures. However, the same thermomechanical behavior that makes nitinol attractive as a functional material presents its own challenges for successful cold spray. This makes a thorough understanding of the feedstock powder even more important than usual when choosing cold spray process parameters. Towards this goal we have characterized several pseudoelastic and pseudoplastic nitinol powders with regard to their microstructure, mechanical properties, and phase-transition behavior. In this work we present some preliminary results as well insights that will translate into better cold spray consolidations. |
