Abstract Scope A class of soft magnetic FeNi-based metal amorphous nanocomposite (MANC) alloys is investigated for their tunability of magnetic permeability through thermal-mechanical processing. Such FeNi-based alloys exhibit a response to external forces during the thermal annealing stage and enhanced mechanical properties as compared to FeSi-based alloys to allow for successful large-scale manufacturing. Here we demonstrate a technique to optimize magnetic properties in toroidal cores wound from flat strain annealed 25-mm wide ribbons of composition (Fe70Ni30)80Nb4Si2B14. A range of tensions from 25 – 250 MPa is applied as a function of ribbon length for a material speed 3.5 cm/s and annealing temperature 440 °C. Dramatic changes in magnetic properties are observed after winding and determined to be of magnetostrictive origin inclusive of casting curvature effects. A procedure to re-anneal the wound toroidal cores to reduce these detrimental effects is developed to optimally achieve core losses equivalent to state-of-the-art FINEMET MANC alloys.
