There has been a push to develop a magnetic material with minimal core loss for use in electric motors to improve efficiency. Laminated silicon steel has been one of the primary materials of interest because of its high permeability and low conductivity which reduces hysteresis loss. These properties can be further enhanced by tuning the microstructure to increase grain boundary scattering and thus resistivity of the material to reduce the need for the non-magnetic laminates. This talk will compare the results of top-down and bottom-up approaches to producing nanograined bulk silicon steels. Samples processed by severe plastic deformation are compared to those processed by high-energy ball milling and sintering. Properties studied include the effect of grain size and grain boundary characteristics on resistivity and permeability. These findings will help to advance electric motor technology by improving efficiencies, and have widespread energy impacts.
