Beginning with the crystallization of amorphous alloys, this paper introduces the newly developed nanocrystalline soft magnetic materials which have excellent properties. The following items are in-volved: (1)The concept of crystallization in amorphous alloys and the effect of crystalline precipitates on the magnetic properties of amorphous alloys. (2)The discovery of Fe-Cu-Nb-Si-B nanocrystalline soft magnetic alloys and their excellent magnetic properties. (3)The origin of the excellent soft magnetic properties in the nanocrystalline alloys. Finally the development trends of these nanocrystalline alloys are discussed.
