| Abstract Scope |
This research investigates the as-deposited microstructure and tensile behavior of multi-layer 304L stainless steel additive friction stir deposition (AFSD) builds. Tensile specimens were machined from 7 layer AFSD builds consisting of 0.5 mm individual layer heights, 30 mm layer widths, and 76 mm long. The AFSD 304L stainless steel deposit showed tensile strengths similar to wrought stainless steel, as well as uniform hardness throughout the layers and substrate. Characterization of the AFSD deposit revealed equiaxed grain structure compared to the substrate. Oxide formation was observed at the layer interfaces, which resulted in lower build-direction tensile ductility. The present study demonstrates AFSD technology as an emerging large scale solid-state, non-melting, additive manufacturing process building 304L stainless steel components. |
