Additive Friction Stir Deposition
Additive Friction Stir Deposition (AFSD) is a solid-state additive process that allows for square metal feedstock to be severely plastically deformed and deposited onto a substrate without melting the feedstock or the substrate. AFSD can be used both for material repair as well as large volume depositions, and we perform our AFSD research on a meld B8 machine. Monotonic tensile tests and microhardness testing are used to test the mechanical properties of the processed materials, and micro- and nano-structure characterization are performed using The University’s SEMs and TEM.
