Abstract Scope Residual stress is an inevitable and often detrimental feature in additively manufactured metals in the as-built condition. To date, Type I residual stress is thoroughly investigated because of its direct influence on the fabrication quality, whereas the subtle Type II residual stress receives little attention, despite its significance in the metal’s mechanical properties, especially the fatigue performance. In this work, we combine several characterization techniques, most notably, Laue diffraction mapping, to probe the intra- and intergranular residual stress in 316L stainless steel made by laser powder bed fusion. It is found that Type-II residual stress possesses dependencies on grain orientation and grain size. The cause of the correlations is the strong thermal gradients during laser fabrication, which is affirmed with the calculated geometrically necessary dislocation density. This study explores an unchartered material feature in metal additive manufacturing through the power of X-ray scattering, laying foundation for a future optimization task.
