Abstract Scope Iron silicon (Fe-Si) alloy sheets possess favorable magnetic properties for use in electric motors and transformer cores. Commercial processing of these sheets involves multiple rounds of hot and cold rolling with intermediate annealing. Previously, a novel, single-step processing approach was used to produce continuous sheets from high silicon (>3wt%Si) Fe-Si alloys using a hybrid cutting extrusion process called large strain extrusion machining (LSEM). LSEM was shown to develop controlled simple shear textures in sheet with variable grain sizes from a range of Fe-Si compositions. In this study, preliminary magnetic properties of the shear-textured Fe-Si sheets are reported using a closed-loop permeameter. Measured properties include maximum relative permeability, coercivity, hysteresis loss, and saturation induction. These properties are evaluated as independent functions of sheet texture, grain size and composition. Implications for controlling the magnetic properties via LSEM are discussed and properties are compared with some expectations from a simple unit cell model.
