The PBF-LB/M-produced 316L has a thermally metastable, anisotropic microstructure with epitaxially grown grains in which a cellular substructure is located. When brazing hybrid joints from the conventional and additive manufacturing routes with nickel-based brazing alloys, different diffusion mechanisms occur simultaneously in both joining partners. This occurs due to the different microstructural characteristics of the parent materials. The altered diffusion mechanisms lead to a new distinct microstructure in the joining zone, which influences the achievable quality of the brazed joint in a previously unknown way.enWelding in the world; 68(9)https://creativecommons.org/licenses/by/4.0/BrazingAdditive manufacturingPBF-LB/MHybrid jointsStainless steelNickel-based brazing alloy620670ResearchArticleHartlötenRapid Prototyping <Fertigung>Selektives LaserschmelzenHybridfügenEdelstahlNickellegierung
