Nanocrystallization of iron-based amorphous alloys Fe82Nb2B14RE2, where RE = Y, Gd,
Tb, Dy, was studied by differential thermal analysis
(DTA) in the temperature range from 300 K to 1300 K. The structure
before and after the first stage of crystallization (~810 K) was checked
by X-ray diffraction (XRD). The measurements allowed determining the temperature and activation
energy of nanocrystallization. In addition, the
influence of magnetization in an alternating magnetic field on the nanocrystallization process in the amorphous alloy Fe82Nb2B14Gd2 was
studied. The
electrochemical changes caused by the alternating magnetic field were
investigated by potentiometry and voltammetry.
