摘要：
The magnetic anisotropy and saturation magnetostriction constant of Fe74Nb3Cu1Si13B9 devitrified under applied stress have been investigated. Various annealing times and temperatures are used to control the amount of nanocrystalline phase. The interpretation of creep-induced anisotropy by magnetoelastic coupling with internal back-stresses in FeSi grains leads to the conclusion that gradual enrichment of FeSi phase in Si takes place with increasing crystalline fraction.
