Nitriding thermochemical treatment (NTT) is used as nanocrystallization met
hod. Such a method slightly improves the nanocrystallization state of Fe73.
5Cu1Si13.5B9(Nb-3) and Fe73.5Cu1Si13.5B9(Zr-3) alloys in comparison with th
e conventional method. The magnetostriction constant obtained either with N
b- or Zr-addition to the FeCuSiB-system is lower than that obtained when th
e sample is annealed conventionally. (C) 2000 Elsevier Science B.V. All rig
