Deposition Characteristics of High-Thermal-Conductivity Steel in the Direct Energy Deposition Process and its Hardness Properties at High Temperatures

Direct energy deposition (DED) is a three-dimensional (3D) deposition technique that uses metallic powder; it is a multi-bead, multi-layered deposition technique. This study investigates the dependence of the defects of the 3D deposition and the process parameters of the DED technique as well as dep...
