摘要： The changes of local structures around Fe and Zr atoms in the nanocrystalline films of Fe85Zr9B6 and Fe84Zr9B6 Cu1 alloys during annealing process were investigated by extended X-ray absorption fine structure (EXAFS) technique. It is confirmed that Zr atoms always exist in amorphous phase and do not dissolve in the bcc α-Fe crystalline phase. The addition of 1 at% Cu lowers the crystallization temperature.

It is confirmed that Zr atoms always exist in amorphous phase and do not dissolve in the bcc $\alpha$-Fe crystalline phase. The addition of 1 at% Cu lowers the crystallization temperature.
