Opis:: Structural changes in Finemet based alloys invoked by germanium replacement for silicon were investigated using the X-ray diffraction, the X-ray absorption spectroscopy and the Mössbauer spectroscopy. Ge substitution preserves a nanostructural character of annealed samples at temperature 550°C; specifically the formation of a $DO_3$-type with about 19 at.% of (Si,Ge) was confirmed. The mean size of nanocrystals was estimated to be about 7 nm.

Opis:: The process of a primary crystallization of the $Fe_{72.5}Cu_{1}Nb_{2}Mo_{2}Si_{15.5}B_{7}$ alloys was investigated by differential thermal analysis (DTA), x-ray diffraction (XRD) and transmission electron microscopy (TEM). Amorphous ribbons were isothermally annealed for 0.5, 2, 6, 30 and 150 minutes at 520 °C. Both, the XRD and TEM study showed that the level of devitrification of the sample increases with the annealing time. The above mentioned techniques confirmed the presence of the nanocrystalline grains of the $Fe_{3}Si$ phase and enable us to study the evolution of the identified phase.
