Оптимизация параметров термической обработки магнитопроводов из аморфного сплава Finemet

Abstract

Critical points of initially amorphous Fe-Si-Nb-Cu-Mo-B-system alloy, produced by rapid cooling method, were determined using calorimetry and non-ambient x-ray diffraction methods. Alloy existence temperature interval in a nanocrystalline state was established. Heating values of phase and structure transformations, which being realized by heating, were determined. Measurements were used for finite difference simulation and heat treatment optimization of twisted magnetic cores of different sizes.
