| Abstract Scope |
The stainless steel-copper composite has been investigated as a structural material in industries where heat transfer is required. This composite exhibits outstanding mechanical properties along with high thermal conductivity. Furthermore, controlling the shape of copper fibers can optimize the properties of stainless steel-copper composite. From this standpoint, additive manufacturing has an advantage of designing of a 3D structure of the composite more effectively compared to conventional methods. In this study, 316L stainless steel-copper composites were fabricated using directed energy deposition. The composite structures were fabricated with the complex structures derived from the 3D cubic lattice structures. The microstructure around the interface were observed using scanning electron microscope. The mechanical and thermal properties of the composites were investigated by tensile test and laser flash apparatus, respectively. Consequently, the properties were compared between composites with different shapes of copper fibers and the reasons for this were analyzed. |
