Abstract Scope |
This talk will describe the deformation microstructures formed when single, refractory metal particles impact a substrate and bond. Cold spray deposition enables solid state production of three-dimensional structures. A single particle impact is the unit operation of cold spray, and it is, therefore, essential to understand how the particle microstructure is transformed by this process. Irregular and spherical tantalum and niobium particles were accelerated to supersonic velocities and then sprayed onto polished stainless steel and refractory metal substrates. Focused ion beam microscopy and electron microscopy are being used to assess the deformation microstructures at the micro- and nanoscales. The nature of the substrate causes distinct changes in the types of deformation features along the particle-substrate interface.
