摘要：
The effects on the evolution of coercivity (H-c) and brittleness in FINEMET-type precursor glasses during traditional (isothermal) and pulse heat treatments are compared. The time and temperature dependences of these quantities are monitored during the series of isothermal and pulse heat treatments. The activation energy for H-c relaxation is lower than that for the brittleness evolution, however, dramatic changes in the values of these quantities can be detected above 300 degrees C. Both quantities change mainly with temperature, they are less time-dependent.
