Evaluating the impacts of surface roughness and microstructure on the size effect in two additively manufactured stainless steels

Materials & Design
Laser powder bed fusion (L-PBF) enables direct manufacturing of components with complex geometries and thin walls, but many authors report size-dependent mechanical properties that may complicate design.
