Abstract:

On the example of soft magnetic Fe(81)B(13)Si(4)C(2) and Fe(77)Ni(1)Si(9)B(13) amorphous alloys, the relation between the level of magnetic properties and duration of isothermal holding in the course of heat treatment in air has been studied. The optimum temperature-dependent time tau of isothermal holding has been shown to be related to the volume fraction of domains (V (orth)) with orthogonal magnetization in the initial (quenched) ribbon by equation V (orth) = tau tau(1/3). A temperature dependence of the proportionality coefficient alpha, which determines the degree of diffusion-process activity, has been determined. The results obtained allow us to substantially simplify the choice of optimum conditions of atmospheric heat treatment of soft magnetic Fe-based amorphous ribbons.
