Abstract Scope |
Sheet production of soft magnetic alloys has been traditionally done by rolling due to its cost advantage compared to other methods. However, rolling introduces workability issues to the production of high-Si iron alloys. These workability issues prevent the low-cost production of sheets with outstanding soft magnetic properties, such as sheets of Fe-6.5Si wt%. Hybrid Cutting Extrusion (HCE) and Free Cutting (FC) present a new alternative for production of sheets of low-loss soft magnetic materials. The combination of a localized deformation zone, large plastic strains, high hydrostatic pressures, and high temperatures enhances the workability, thus suppressing the deformation mechanisms that lead to cracking in rolling. For this study, thin strips of Fe-4Si, Fe-6.5Si, Fe-3Si-3Al, and Fe-4Si-4Cr alloys were produced using HCE and FC. Characterization shows quality of the strips in terms of surface roughness, microstructure control and properties. |
