Abstract

Directed Energy Deposition (DED) is fundamentally an additive manufacturing (AM) technique, capable for the fabrication of Fe-Si soft magnetic materials, which are important for transformers, motors and other energy structures. This study utilizes optical microscopy (OM), X-ray Diffraction (XRD), Electron Backscatter Diffraction (EBSD) and Vickers microhardness testing for the microstructural and mechanical investigation of DED Fe-Si alloy. This study demonstrates the fabrication consists of detrimental porosity, cracks, characteristic columnar grain growth, and predominant BCC Fe, Si and SiO₂. The crystallographic texture 〈001〉 corroborates DED’s ability to tailor soft magnetic materials for easy magnetization.
