Abstract Scope |
The Laser Powder Bed Fusion (LPBF) process for the novel structural AL-Fe-Zr alloy, AheaddŽ CP1, by Constellium was investigated in-situ during synchrotron x-ray microtomography at the ESRF/BM18 beamline using a miniature LPBF machine. The data obtained provides information on defect morphology and size distribution, as well as build quality as a function of printing strategy and geometry. Moreover, information about the porosity history from layer to layer that cannot be easily obtained by other methods was acquired. It was observed that the LPBF process is a partially self-healing process, i.e., pores formed in one location can heal after a few more layers are built up, while other pores form. This experiment allows for the understanding of the underlying mechanisms and provides suitable data, such as morphology and distribution of defects depending on material, printing parameters and sample geometry, for the validation of AM simulation models. |
