Additive manufacturing (AM) enables the fabrication of complex engineering components previously inaccessible through traditional manufacturing processes. It is established that AM process parameters affect the formation of defects and the as-built microstructure. This physics is well studied and has been exploited to enable the control of microstructure in electron beam melted (EBM) materials. A relatively less understood phenomena is the geometry dependence on defects and microstructure. Even inclined printing of simple prismatic geometries can promote cracking unobserved in vertically printed parts. Therefore, geometry dependence poses a significant challenge towards unlocking the full potential of AM in fabricating complex engineering components. In this talk we present recent work on AM EBM Ni-based superalloys and the influence of geometry on process-structure-property relationships. This research was sponsored by DOE Office of Fossil Energy, Crosscutting research program, and the Office of Energy Efficiency and Renewable Energy, Advanced Manufacturing Office.
