Abstract Scope |
Laser Additive Manufacturing has the potential to revolutionize manufacturing processes. At the ESRF, taking advantage of the recent Extremely Brilliant Source upgrade and the most advanced synchrotron material characterisation techniques, we established a well-rounded picture of the LAM process. Fast X-ray imaging enables the observation, in both real and reciprocal space, of the laser-matter interaction, defects formation, material phase transformations, and microstructural features evolution. High angular resolution Dark Field X-ray Microscopy and 3D-XRD are used to quantify the resulting LAM microstructure including spatially resolved 3D grain maps, 3D distribution of strains, lattice misorientation and Geometrically Necessary Dislocations. The results presented here provide new insights into the LAM process with relevance to microstructure and defects control in AM fabricated components. They provide information that can contribute directly to industrial practice while producing quantitative data to inform and validate physical models in support of digital twins. |
