Abstract Scope |
Additive manufacturing (AM) has transformed the production of intricate components by offering design flexibility and waste reduction. Directed Energy Deposition (DED) process, allows for the localized deposition of material, enhancing the fabrication of high-performance components. The inherent residual stresses and inhomogeneity in the microstructure necessitate post-manufacturing optimization to acquire desired properties. The study aims to provide a comprehensive insight into the potential benefits of utilizing AM for steel manufacturing. This paper offers an extensive study on the heat treatment optimization of AISI 5120 low alloy steel, manufactured using the LMD additive manufacturing process, to enhance the microstructural and mechanical properties; with an aim to achieve AAR M201 Grade B properties. The study includes the processes of additive manufacturing and heat treatment of the AISI 5120 powdered low alloy steel. Additionally, the microstructure and mechanical properties of as-printed and heat treated conditions were compared to the ARR grade B specification |
