| Abstract Scope |
Fe-Si (i.e., electrical steel) alloys possess favorable electromagnetic properties, such as high magnetic permeability/saturation induction, low coercivity/core loss and high electrical resistivity, ideal for electric motors and transformers. The addition of Si into Fe enhances the electromagnetic properties to create more efficient power devices, with peak alloy performance near 6.5 wt.% Si. Unfortunately, despite opportunities for enhancing energy efficiency via the use of high-Si content electrical steels, widespread commercial adoption of this alloy composition has yet to be achieved due to poor material ductility, making conventional manufacturing impractical. Laser beam directed energy deposition (LB-DED) additive manufacturing (AM) is presented as a viable route for producing bulk geometries of a high Si-content Fe-6wt.%Si alloy. Microstructure and magnetic properties of the LB-DED Fe-6wt.%Si alloy are characterized and benchmarked against wrought low-Si and other AM-processed high-Si content alloys.
