摘要：
The size of the crystalline nanograins and the thermal stability of nanocrystalline Fe-Co-Nb-B-(Cu) alloys decrease as the heating rate at which the nanocrystalline microstructure is developed increases. Mossbauer experiments performed at room and high temperatures (473 and 673 K) show no differences in the crystalline contribution of samples prepared at different heating rates, although a slight decrease of the average hyperfine fields assigned to the interface contribution is detected for samples nanocrystallized at a higher heating rate.
