| Abstract Scope |
Over the past few years there has been substantial effort on developing Fe-3.8wt%Si grain oriented electric steels using laborious conventional techniques which include multi-step rolling for applications in transformers. Further, high silicon Fe-6.5wt%Si electric steels have gained significant traction because of their excellent magnetic properties. The brittle nature of the high silicon steels resulted difficulty in manufacturing via conventional techniques. In the present study, we explored the possibilities of producing Goss oriented Fe-3.8wt%Si and Fe-6.5wt%Si high silicon electric steels using Direct Energy Deposition (DED) and Laser Powder Bed Fusion (LPBF) additive manufacturing techniques. The DED and LPBF processed Fe-3.8wt%Si steels exhibited <001>BCC texture along the build direction which resulted in better magnetic properties compared to the conventionally processed counterpart. On the other hand, the DED deposited Fe-6.5wt%Si steel exhibited a single phase DO3 ordered microstructure which led to good soft magnetic and decent mechanical properties. |
