In the first part of this paper, the metallurgical background of the amorphous-nanocrystalline transformation leading to the development of soft magnetic properties is discussed. The mechanisms of nucleation as well as grain growth hindering will be treated on the basis of metallurgical principles. The development of some technical magnetic properties during the nanocrystallization such as the loss characteristics and the change in the domain structure will be compared. Finally, the development of the field-induced anisotropy obtained during different heat treatments will be compared for the FINEMET-type and Fe-Zr based nanocrystalline alloys.
