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 metal structures with H13 tool steel and 316L stainless steel powders using directed energy deposition additive manufacturing method. The additively manufactured laminated steel structures exhibit multiscale and hierarchical lamellar microstructures that are tunable, leading to superior synergy of strength and ductility. Microstructural heterogeneity and its resultant hetero-deformation induced strengthening and toughening mechanisms in the additively manufactured heterostructured samples are examined. This work provides new insights to design and directly manufacture high-performance bulk heterostructured materials via additive manufacturing. |
