Orientation solidification map through laser scan strategy Engineering for additively manufactured stainless steels

Using a three-dimensional multiphase finite element model combined with a multiscale characterization framework, this study investigates the solidification characteristics and grain orientations of 316L stainless steel (316LSS) during laser powder bed fusion (LPBF) under different laser scanning strategies. Three common patterns—meander, stripe, and chessboard—were evaluated to capture the associated thermal profiles and melt pool (MP) …
