Cold Spray Additive Manufacturing of a Ti-Zr-Ni shape memory alloy for future large deployable aerospace components.

Shape Memory Alloys (SMA) are smart materials capable of recovering large inelastic strains. SMA are therefore excellent candidates for applications where deformation needs to be controlled remotely. One of the main challenges holding back a wider acceptance of SMA is their poor workability leading to high tool wear when manufactured by machining. Additive Manufacturing, also known as 3D printing, is an alternative to subtractive shaping processes as it offers a solution to build complex near net shape components requiring minimum to no machining. In this project, the properties of a Ti-Zr-Ni shape memory alloy produced by Cold Spray Additive Manufacturing (CSAM) will assessed. The investigation will provide crucial information to conclude if Ti-Zr-Ni CSAM is a good candidate for large deployable parts.
