Iron silicon (Fe-Si) alloy sheets possess favorable magnetic and electrical properties for uses in electric motors, relays and transformer cores. Commercial processing of Fe-Si sheet is typically complex, requiring multiple steps of rolling and annealing. Furthermore, compositions are generally limited to alloys containing nominally 3 – 4 wt% Si due to excessive cracking during rolling. To demonstrate successfully avoiding these commercial restrictions, thin (t < 150 micron) Fe-Si strip are produced from high silicon (> 3.5 wt%) alloys by large shear deformation via hybrid extrusion-machining. Strips produced are characterized in terms of grain size and crystallographic orientation (texture). Anisotropic magnetic properties of the shear-textured strips are predicted based on measurements of single crystal data for Fe-Si of similar compositions. Results are compared with grain-oriented and non-grain-oriented commercial grades.
