Manufacture of high performance soft magnetic materials by melt spinning

The methodology is to design a master alloy with different starting compositions, to which Fe is added to get the desired atomic ratio of components. With this starting alloy, using the method of melt spinning, are achieved amorphous ribbons (FeSiB) with desired soft magnetic behavior. Then these ribbons are thermally treated for achieve nanocrystalline structures to improve the performance in the magnetic cores.
