Abstract

Electrical current annealing based on the Joule-heating technique, known also as the thermal electrical resistivity method, was applied for nanocrystallyzation of the Fe73.5Nb3Cu1Si15.5B7 amorphous ribbon. The feature of the Joule-heating technique is high heating rates of the material internal volume that in the case of amorphous alloys causes the evolution of the metastable amorphous state. Structure transformation was investigated by the X-ray diffraction method, which allows obtaining the phase composition of the material as well as nanograin size. The nanocrystalline phases that precipitate during current annealing are Fe3Si and hexagonal phase with a nanoscale grain size, the average value of which tends to depend on annealing duration as well as applied voltage and varies in the range of 10–200 nm. Field-emission scanning electron microscopy was used to investigate the surface topology and nanograins, and at some samples, petal-like structures were observed on the ribbon’s surface after the Joule-heating technique application. Saturation magnetization and microhardness were studied in relation to electrical current parameters, and optimal values were observed for its improvement. Obtained results could be helpful for controlling the conditions of the formation of fully or partially nanocrystalline structured materials from amorphous ribbons based on Fe-Si-B-Nb-Cu.
