Amorphous Fe73.5Nb3Cu1Si13.5B9 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
