Abstract

Electroforming is a process that employs technology similar to that used for electroplating but which is used for manufacturing metallic articles, rather than as a means of producing surface coatings. Electroforming provides a cost-effective means of producing alloys and fully dense nanocrystalline metals as foils, sheets and complex shapes. Fe-Ni nanocrystalline alloy foils with composition in the $36\~80wt\%$ Ni range were fabricated by electroforming. The thickness of electroformed foils was in the range of $5\~30{\mu}m$. TEM and XRD analysis was applied for measuring the grain size. Very fine grain size$(\~10nm)$ was obtained in alloy foils. The yield and tensile strength of electroformed Fe-Ni alloy were 2000-2800 MPa and 2500-3300 MPa respectively. The magnetic permeability at high frequency of electroformed Fe-Ni foil was higher than that of thicker foils.
