Laser-powder bed fusion (LPBF) enables the fabrication of complex metallic components by manipulating various laser scan strategies to control microstructure and texture. During processing, multiple thermal cycling and rapid solidification lead to non-equilibrium, non-uniform microstructure in the melt pool and elemental micro-segregation at the melt pool boundary (MPB). However, the characterization of the MPB's accurate localization and the quantitative analysis of segregation behavior at the MPB remain unsolved. In this study, we controlled the crystallographic texture of 316L stainless steel (316LSS) by unique LPBF processing parameters, successfully observed the accurate location of the MPB, and extracted the quantitative concentration using high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) with energy-dispersive X-ray spectroscopy (EDS). Compared with cellular interiors, Cr and Mo were depleted by 0.5-0.7wt%, Mn and Ni were depleted by 0.1-0.3wt%, while Fe was enriched by 1.5wt% at the MPB, which are qualitatively similar to the Scheil-Gulliver solidification simulation results.
