Abstracto
High-temperature in situ Mössbauer spectroscopy was used to investigate the nanocrystallization process in Fe73.5Si13.5B9Cu1Nb1X2 (X=Zr, Nb, Mo and V) amorphous alloys. The Mössbauer spectra were taken at temperatures where only the amorphous phase is found in a paramagnetic state, allowing an accurate resolution between the amorphous and crystalline phases presented in the annealed ribbons.
