Using the induction melting combined with injection copper mold casting, fully amorphous (Fe<sub>36</sub>Co<sub>36</sub>B<sub>19.2</sub>Si<sub>4.8</sub>Nb<sub>4</sub>)<sub>99.5</sub>Cu<sub>0.5</sub> rods with diameters up to 2 mm and a length of 5 cm were successfully cast. If the base composition forms by primary crystallization Fe<sub>23</sub>B<sub>6</sub>-type phase, the addition of Cu drastically change the thermal behavior. Upon heating the new glassy alloys gradually forms (Fe,Co) solid solution. Further, the dimension and the volume fraction of the bcc crystals control the soft magnetic properties. The precipitation of bcc (Fe,Co) takes place within a temperature interval of 100 K, with high nucleation rate at the initial stage. The present work aimed to explore the mechanism of phase formation upon heating by means of time-resolved X-Ray diffraction in transmission configuration using synchrotron radiation. Based on these results, new annealing treatments were defined and the resulted structures and soft magnetic properties in details analyzed.
