The changes of local structures around Fe and Zr atoms in the nanocrys
talline films of Fe85Zr9B6 and Fe84Zr9B6 Cu-1 alloys during annealing
process were investigated by extended X-ray absorption fine structure
(EXAFS) technique. It is confirmed that Zr atoms always exist in amorp
hous phase and do not dissolve in the bce alpha-Fe crystalline phase.
The addition of 1 at% Cu lowers the crystallization temperature.
