摘要：
Transmission Fe-57 Mossbauer spectrometry was used to study the microstructural and magnetic changes induced by neutron irradiation of nanocrystalline Fe-Zr-B alloy. Measurements were performed in the temperature range from 77 K up to 500 K. The evolutions of both the hyperfine field distribution, the average hyperfine field value, the mean orientation of the ferromagnetic domains and the value of the Curie temperature are consistent with short-range atomic order changes resulting from the neutron irradiation damages. In addition, the neutron irradiation affects significantly the proportions of amorphous, crystalline and interfacial phases. The results of Mossbauer spectrometry were correlated with those obtained by X-ray diffraction.
