Abstract
Four Fe73.5Nb3Cu1Si13.5B9 ribbons obtained by melt spinning with diffe rent quenching rates were submitted to direct current (DC) Joule-heati ng treatment in vacuum. On-line measurements of the electrical resista nce were performed in the course of Joule heating in order to study th e development of the nanocrystalline phase. The results show that the nanocrystallization kinetics is strongly dependent on the initial degr ee of structural disorder. The increase in both initial magnetic perme ability and brittleness upon nanocrystallization were observed to be a ffected by the initial topological disorder.
