| Abstract Scope |
In the laser-based additive manufacturing (PBF-LB) process of AlSi10Mg components, the layer-by-layer deposition leads to microscopic and macroscopic thermal effects (shrinkage, residual stresses, overheating) depending the component geometry. This results in a strong dependence of the microstructure and therefore of the process-induced material properties on the shape of the manufactured component. To analyze this behavior, components with different geometric aspects, such as various construction angles, were built in the PBF-LB process. In order to perform a spatially-resolved characterization and evaluation of the mechanical behavior of the component, small-scale tensile specimen in the sub-millimeter range were manufactured from representative areas of the components. With the obtained results, design approaches based on local material data can be improved significantly. |
