Abstract Scope |
Additive manufacturing (AM) is known for the complexity of its processing parameters that greatly influence the materials properties such as porosity, residual stresses, microstructure and mechanical behavior. Neutron-based experimental methods are particularly important for characterizing the bulk material in AM components non-destructively, due to their high penetrability. Synergy of multiscale characterization techniques is applied for studying AM components within the Neutron Imaging and Applied Materials group at the Paul Scherrer Institute. Neutron diffraction studies are undertaken at the instrument POLDI for residual stress characterization and in-situ investigations of the deformation behavior of AM materials. The imaging beamlines ICON and NEUTRA and the novel “Neutron Microscope” are employed for the characterization of the internal structures in length-scales ranging from about 10 microns to cm. Finally, diffraction contrast imaging on the BOA beamline is undertaken for mapping the phase, strain and texture distribution with high spatial resolution. |
