Abstract:
A method of making a soft magnetic material with fine grain structure is provided. The method includes the steps of providing a soft magnetic starting material; heating the soft magnetic starting material to a temperature at which the material has a microstructure comprising at least two solid phases; and deforming the soft magnetic starting material. An electrical device comprising a magnetic component is provided. The magnetic component comprises a soft magnetic material having a grain size less than about 3 micrometers. The material has a composition that comprises at least two solid phases at temperatures greater than about 500° C.
