Abstract: Method for manufacturing a thin strip in a soft magnetic alloy and strip obtained A method for manufacturing a strip in a soft magnetic alloy capable of being cut out mechanically, the chemical composition of which comprises by weight: 18% ≤ Co ≤ 55% 0% ≤ V + W ≤ 3% 0% ≤ Cr ≤ 3% 0% ≤ Si ≤ 3% 0% ≤ Nb ≤ 0.5% 0% ≤ B ≤ 0.05% 0% ≤ C ≤ 0.1% 0% ≤ Zr + Ta ≤ 0.5% 0% ≤ Ni ≤ 5% 0% ≤ Mn ≤ 2% The remainder being iron and impurities resulting from the elaboration, according to which a strip obtained by hot rolling is cold-rolled in order to obtain a cold-rolled strip with a thickness of less than 0.6 mm.After cold rolling, a continuous annealing treatment is carried out by passing into a continuous oven, at a temperature comprised between the order/disorder transition temperature of the alloy and the onset temperature of ferritic/austenitic transformation of the alloy, followed by rapid cooling down to a temperature below 200° C. Strip obtained.

Abstract: Disclosed is a basic module of a magnetic core of a wound electrical transformer. The basic module includes first and second windings placed atop one another and made of first and second materials, respectively. The first material is a crystal having a saturation magnetization ≧1.5 T and magnetic losses less than 20 W/kg in sine waves having a frequency of 400 Hz, for maximum induction of 1 T, and the second material is a material having an apparent saturation magnetostriction less than or equal to 5 ppm and magnetic losses less than 20 W/kg in sine waves having a frequency of 400 Hz, for maximum induction of 1 T. The cross-sections of the first winding and cross-sections of the second winding satisfy (S1/(S1+S3); S2/(S2+S4)) of the first material, having a high saturation magnetization, compared to the cross-section of both materials together, is 2%-50%.
