Abstract

The process of isothermal crystallization of Fe73.1Si15.5B7.4Nb3.0Cu1.0 amorphous alloy at T=723K was studied by means of an X-ray diffraction method. The diffraction data were collected at various instants of the crystallization process, resulting in the time dependence of parameters determining the nanocrystaline structure (volume fraction, X(t), mean size, L(t) and concentration of nanocrystals, N(t)). The experimental data for analyzing the crystallization kinetics were employed using the Johnson- Mehl-Avrami approach.
