dc.description.abstract | In this paper the influence of copper addition on the formation of the amorphous phase and the nanocrystallization
process of Fe79.8−xCo2CuxMo0.2Si4B14 (x=0, 0.25, 0.5, 0.75, 1, 1.5, 2) ribbons was described. The
formation of crystalline phases was described using differential scanning calorimetry, X-ray diffractometry,
Mössbauer spectroscopy and transmission electron microscopy. It was confirmed that the addition of copper
decreases the glass forming ability, while facilitating the process of nanocrystallization. The analysis of the
Avrami exponent allowed to state, that for fully amorphous alloys the crystallization of the α-Fe phase is associated
with diffusion-controlled growth with decreasing nucleation rate and the Fe2B phase with interface
controlled growth with increasing nucleation rate. Additionally, with increasing copper addition onset temperature
of crystallization of α-Fe phase shifts to lower values, whereas for second, Fe2B phase, these changes are
not so visible. Optimization of the annealing process of toroidal cores made from amorphous ribbons with
different copper content allowed to obtain nanocrystalline, soft magnetic materials characterized by low coercivity
~9 A/m and high saturation induction of about 1.6 T. Analysis of transmission electron microscope images
and electron diffraction confirmed that high magnetic parameters are related to the coexistence of the amorphous
and nanocrystalline phases, which was confirmed also by Mössbauer spectroscopy. | pl_PL |
