| Abstract Scope |
In recent years, significant effort has been dedicated to the development of high-silicon Fe-6.5wt%Si electric steels using casting and forging methods due to their outstanding magnetic properties. The challenges encountered during conventional manufacturing can be attributed to the presence of ordered phases such as B2-FeSi and D03-Fe3Si, which contribute to the brittleness of these steels. In this study, we investigated the feasibility of producing Fe-6.5wt%Si high-silicon electric steels using additive manufacturing (AM), specifically Direct Energy Deposition (DED) and Laser Powder Bed Fusion (LPBF). Both, DED and LPBF processed Fe-6.5wt%Si steels exhibited excellent magnetic properties, including low coercivity and high saturation magnetization. The DED processed Fe-6.5wt%Si exhibited a strong <111> texture parallel to the build direction. Whereas, the LPBF processed Fe-6.5wt%Si showed a <001> texture parallel to the build direction. The presence of B2 and D03 ordered phases is observed in both the DED and LPBF processed Fe-6.5wt%Si. |
