Structural and magnetic study of nitrogenated FeCu–(Nb,Zr)–SiB ribbons

Nitriding thermochemical treatment (NTT) is used as nanocrystallization method. Such a method slightly improves the nanocrystallization state of Fe 73.5 Cu 1 Si 13.5 B 9 (Nb 3 ) and Fe 73.5 Cu 1 Si 13.5 B 9 (Zr 3 ) alloys in comparison with the conventional method. The magnetostriction constant obtained either with Nb- or Zr-addition to the FeCuSiB-system is lower than that obtained when the sample is annealed conventionally.
