Abstract

The effects of high current density electropulsing on the hyperfine structure of amorphous alloys Fe73Si9.5B17.5, Fe75Si10B15, and Fe79Si7B14 were investigated by Mössbauer spectroscopy. Electropulsing influenced the microstructure at a temperature well below the bulk crystallization temperature. In the alloy having least boron (or highest concentration of Fe), α-Fe particles ≃3 nm in size precipitated from the amorphous matrix, giving a change in internal magnetic field.
