The application 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 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). 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.

Method For Creating An Iridescent Visual Effect On The Surface Of A Material, Devices For Carrying Out Said Method, And Part Obtained Thereby
Method for creating an iridescent visual effect on the surface of a part, using a laser beam having a pulse duration of less than a nanosecond sent onto said surface in the optical field of the focusing system of a device comprising also a laser source and a scanner, to apply wavelets having the same orientation to said surface over the pulse width. The scanner scans the surface using laser radiation along a series of consecutive lines, or a matrix of points using relative movement of said surface and the device, the width of each line or the dimension of each point of each matrix being equal to the pulse diameter. Between the carrying out of the scanning along two consecutive lines or two adjacent points the polarization of the laser beam is modified to create wavelets having different orientations on two consecutive lines or two adjacent points.

Method for the creation of an iridescent effect on the surface of a material, and devices for carrying out said method
A method for creating an iridescent effect on a surface through formation of wavelets on the source can include using a pulse of laser beams sent to the surface in juxtaposed optical fields of a focusing system. A scanner scans the surface using laser beams along a series of lines that follow each other in a relative direction of travel of the part and of the scanner and a series of lines that lie in continuation of each other in a direction perpendicular to the relative direction of travel. The optical fields overlap in an overlapping area having a width that is twice the diameter of the pulse laser beam up to 2 cm. Two lines lying in continuation of each other overlap at a junction and between the two series of lines follow each other in a relative direction of travel of the part and the scanner.
METHOD FOR FABRICATING A SUBSTANTIALLY EQUIATOMIC FECO-ALLOY COLD-ROLLED STRIP OR SHEET, SUBSTANTIALLY EQUIATOMIC FECO-ALLOY COLD-ROLLED STRIP OR SHEET, AND MAGNETIC PART CUT FROM SAME
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 FeCo-alloy cold-rolled strip or sheet. A fully recrystallised 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 ≤ 1 mm. Intermediate annealing is carried out when running, leading to a partial recrystallisation 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 at least at 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 recrystallisation 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.
