“…To over come the separation of amorphous phase in the alloy, the concentrations of amorphizing components (Si, B) should be increased. Moreover, it is of interest to additionally use other elements, in particular gal lium, which is known [18] to favor the homogeneity of solid solutions.…”

The effect of the composition and annealing temperature on the structure and magnetic properties of soft magnetic nanocrystalline Fe-Cu-Nb-Mo-Si-B alloys has been studied. An increase in the iron content compared to that in the traditional FINEMET alloy is shown to allow one to increase the magnetic induction by 18% at a coercive force of no less than 6 A/m. It has been found that, along with the amorphous phase, rapidly quenched ribbons of alloys enriched in Fe contain crystalline α Fe based phase precipitates, the (100) crystallographic directions of which are perpendicular to the ribbon plane. Thermomagnetic anal ysis and differential scanning calorimetry were used to determine the temperatures of structural and magnetic phase transformations of the alloys with different iron contents. It was found that the separation of amor phous phase into areas of different compositions precedes the precipitation of nano sized soft magnetic Fe⎯Si phase grains in the rapidly quenched iron enriched ribbons.
