摘要：

Melt-spun FeCuNbSiB ribbons were annealed at 540-550-degrees-C for various times (less-than-or-equal-to 1 h). The development of a nanocrystalline structure was investigated by means of Mossbauer spectroscopy. From measured hyperfine fields and intensities the crystalline phase was inferred to be pure Fe1-xSix, with x=0.18 after 1 h annealing. The residual amorphous volume fraction was determined to be congruent-to 50%. With help of these results it has been possible to evaluate the amorphous contribution to magnetostriction in the nanocrystalline state. The development of a nanocrystalline structure was found to play a role in the main mechanisms of magnetic disaccommodation.
