| Abstract | Fe75Co5Zr10B10 amorphous alloy prepared by melt-spinning was annealed at various temperatures. The thermal property and microstructures were investigated by di erential thermal analysis, X-ray di raction, and transmission electron microscopy. The crystallization process of Fe75Co5Zr10B10 amorphous alloy is complex. The α-Fe phase precipitates from the amorphous matrix in the initial stage of crystallization. The α-Mn type (χ) phase precipitates at 570 ◦C, but transforms to α-Fe phase and the Laves C14(λ) phase at higher temperature. In the nal stage of crystallization, Fe3Zr, Fe2Zr, and unknown phases are observed and the λ-phase disappears. The α-Fe phase preferentially nucleates after annealing at 530 ◦C for 10 min and the χ-phase preferentially nucleates after annealing at 600 ◦C for 10 min. The nucleation barrier of χ-phase is larger than that of α-Fe phase. The local structure of χ-phase is more similar to amorphous phase. |
