中文摘要	A nanocrystalline (NC) fcc FeZr2 intermetallic compound was formed by completely crystallizing the melt-spun amorphous Fe(33)Zr(67)alloy ribbons. The nanocrystallization kinetics and microstructures of the crystallized products were characterized by means of differential scanning calorimetry (DSC), X-ray diffraction (XRD), transmission electron microscopy (TEM) and optical microscopy. The NC fcc FeZr2 samples were formed with grain sizes ranging from 11 to 24 nm, of which the microstrains were found to be extremely small (< epsilon(2) >(0.5) less than or equal to 0.05%). The lattice parameters of the NC fcc FeZr2 were measured in different grain sized samples. Avrami exponents and activation energies of the nanocrystallization process were determined, indicating the transformation began with a 2-D surface crystallization process at the free side of the ribbon followed by 3-D grain growth.
