Experiments on the crystallization of amorphous Fe−Si−B alloys were carried out by thermogravimetric analysis (TG). This new
method gives us some important information about the magnetic phase transformation of amorphous alloys, especially the magnetic
volume change in crystallization beside the energy change obtained by the traditional DSC and DTA methods. Crystallization
activation energies of Fe−Si−B amorphous alloy are calculated from both TG and DTA curves. The experiment also showed that
the addition of Nb, Cu and Mo would influence the crystallization transition temperature of amorphous Fe−Si−B alloys greatly.
