Processing of electrical steel (i.e., iron-silicon) alloys containing up to 6.5wt%Si into sheet is demonstrated by application of highly confined shear deformation in the form of metal cutting. Iron-silicon (Fe-Si) alloys, of major interest to electromagnetic applications, are characterized by poor workability. Through the interactive combination of simple shear, high strain rates, near-adiabatic heating and large hydrostatic pressure in the deformation zone, sheet and foil forms of bulk Fe-Si workpieces are created in a single deformation step.
