The behavior of Cu during the crystallization processes in Fe-Zr-B amorphous alloy was studied by atom probe field ion microscopy and transmission electron microscopy. It was found that Cu atoms formed clusters prior to the crystallization reaction. During the crystallization, Cu enriched clusters provided nucleation sites for α-Fe phase so that the nucleation density of α-Fe phase is increased.
