Amorphous Fe[sub 73.5]Nb[sub 3]Cu[sub 1]Si[sub 13.5]B[sub 9] ribbons were submitted to fast direct current (dc) Joule-heating treatment in vacuum. The electrical resistance in the course of fast Joule heating displays distinctive features during the development of the nanocrystalline phase, which are explained using a recently developed theoretical model. The experimental parameters of the current annealing were optimized in order to obtain ductile soft magnetic materials using very high heating rates.
