| Abstract Scope |
Laminated metal structure is a conventional form of heterostructured materials, which consists of alternating layers of soft and hard metallic phases. Here, we design and build novel laminated metals with H13 tool steel and 316L stainless steel powders using directed energy deposition additive manufacturing method. The additively manufactured laminated steel structures exhibit multiscale hierarchical lamellar microstructures that leads to superior synergy of strength and ductility. Microstructural heterogeneity and its resultant hetero-deformation induced strengthening and toughening mechanisms are characterized using correlative scanning electron microscopy-electron backscattered diffraction (SEM-EBSD) and digital image correlation (DIC) methods. This work provides new insights to design and directly manufacture sustainable yet high-performance bulk steel structures via additive manufacturing. |
