Abstract

Rapidly quenched Fe-Cr-P-C amorphous alloys irradiated with 209 MeV energy 84Kr ions were investigated by Mössbauer spectroscopy, X-ray diffraction, and differential scanning calorimetry measurements. Significant changes were found between Mössbauer spectra of the irradiated and non-irradiated amorphous alloys. The changes were analysed by the hyperfine field distribution method, too. The crystallisation temperature as well as the phase composition at a certain stage of crystallisation were found to be different in the non-irradiated and irradiated samples. These results reflect the changes in the short-range ordering due to the irradiation with energetic heavy ions.
