Abstract Scope |
Microstructural evolution during advanced manufacturing (AM) processes provides beneficial material development opportunities. AM techniques provide a unique opportunity to fabricate complex components which, if optimally designed, may provide options for new generation nuclear reactors to be more competitive. Specifically, AM processes with localized heat controlling abilities, can result in tailored non-equilibrium phases and fine-grained structures. Nevertheless, solid state and solid phase manufacturing processes, may have additional advantages like minimized residual stresses, homogeneous distribution of grain and phase structures. Possibilities also exist in the tailoring of phases through deformation features and therefore provide complimentary application space. Microstructure consistency and repeatability is a key feature for decision-making for identifying manufacturing processes. This presentation compares microstructural features of 316L stainless steel samples from different AM techniques, fused filament fabrication (FFF), digital light photoluminescence (DLP), powder based direct energy deposition (DED), Shear Assisted Processing and Extrusion (ShAPE™), cold spray, and friction stir additive processes. |
