Abstract Scope |
Laser powder bed fusion (LPBF) is an additive manufacturing (AM) technique widely used within the aerospace and medical industries due to its ability to print complex geometries at low cost. However, the microstructure of these printed parts is highly variable both within a single print and across different print parameters. TriBeam tomography, a 3D characterization technique that incorporates a femtosecond pulsed laser with an FIB SEM for serial sectioning of mm3-scaled samples with sub-µm resolution, has particular utility for investigating the multiscale microstructural features that exist in AM material. In this work, a novel cobalt nickel superalloy printed via LPBF is reconstructed using the TriBeam, generating a large dataset in which orientation data, such as grain reference orientation deviation, and morphology data, such as grain size, is examined. Comparisons between the CoNi materials and 3D datasets collected from material printed with alternative AM methods and processing parameters will be discussed. |
