Abstract

X-ray studies of nanocrystallisation process in the Fe-Nb-B amorphous alloy are studied. The samples were annealed in argon atmosphere in a range of temperatures till 1025 K. The first diffraction lines typical for αFe were detected after annealing at 740 K temperature. The full crystallisation was observed after annealing at 1025 K/1h and leaded to formation of αFe crystalities and borides Fe3B and Fe2B as well. It was also shown that the enhancement of soft magnetic properties (optimisation) effect studied for the same samples takes place at lower temperatures than the nanocrystallisation.
The essential aim of the presented paper is to study a correlation between magnetic properties of the Fe-Nb-B amorphous alloy and a degree of advancement of the nanocrystallisation process examined in detail by applying X-ray technique. The determination of the nano-grain size and magnetic permeability for the same samples should allow controlling the nanocrystallisation process, thus in other words, it should allow controlling material properties.
