The mechanical properties in laser-based powder bed fusion (PBF-LB/M) manufactured parts are anisotropic in nature due to the layer-wise build-up but also change due to different solidification conditions in dependence on the process strategy and the

Publikováno v: Physical Review Applied. 11

Evaluation of microstructure in metallic alloys following solidification in laser powder-bed fusion, an additive-manufacturing process, is challenging due to high growth velocities, typically on the order of cm/s. This theoretical analysis of experim
