Abstract: The invention relates to a substantially equiatomic FeCo-alloy cold-rolled strip or sheet, and to a magnetic part cut from same, as well as to a method for fabricating a Fe—Co-alloy cold-rolled strip or sheet. A fully recrystallized hot-rolled sheet or strip is prepared, with a thickness of 1.5-2.5 mm and the following composition: 47.0%≤Co≤51.0%; traces≤V+W≤3.0%; traces≤Ta+Zr≤0.5%; traces≤Nb≤0.5%; traces≤B≤0.05%; traces≤Si≤3.0%; traces≤Cr≤3.0%; traces≤Ni≤5.0%; traces≤Mn≤2.0%; traces≤O≤0.03%; traces≤N≤0.03%; traces≤S≤0.005%; traces≤P≤0.015; traces≤Mo≤0.3%; traces≤Cu≤0.5%; traces≤Al≤0.01%; traces≤Ti≤0.01%; traces≤Ca+Mg≤0.05%; traces≤rare earths≤500 ppm; the remainder being iron and impurities. A first cold-rolling step is carried out with a reduction rate of 70 to 90%, to bring the strip or sheet to a thickness of ≤1 mm. Intermediate annealing is carried out when running, leading to a partial recrystallization of the strip or sheet, running at a speed (V), and where its temperature, in the useful zone of the furnace of useful length (Lu), is between Trc and 900° C., the strip or sheet remaining therein for 15 s to 5 min at a temperature (T) such that 26° C.·min≤T−Trc)·Lu/V≤160° C. min. The strip or sheet is cooled to at least 600° C./hour. A second step of cold-rolling the annealed strip or sheet is carried out, with a reduction rate of 60 to 80%, to bring the strip or sheet to a thickness of 0.05 to 0.25 mm. And final annealing (Rf) of the cold-rolled strip or sheet is carried out to achieve complete recrystallization followed by cooling at 100 to 500° C./hour.
Magnetic part, such as a magnetic core, obtained from a strip or sheet manufactured by this method.

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%.
