摘　　要：对采用单辊快淬法制备Fe86Zr5Nb1B8和Fe86Zr1Nb5B8非晶纳米晶合金薄带在不同温度下进行退火处理。利用X射线衍射仪和扫描电镜研究合金的微观结构。结果表明：Fe86Zr5Nb1B8和Fe86Zr1Nb5B8合金的自由面存在α-Fe相（200）晶面择优取向;随着退火温度的升高,Fe86Zr5Nb1B8和Fe86Zr1Nb5B8合金自由面和贴辊面α-Fe相的平均晶粒尺寸变化比较复杂。Fe86Zr5Nb1B8 and Fe86Zr1Nb5B8 amorphous-nanocrystalline alloys prepared by melt-spinning were annealed at different temperatures. The microstructure of the alloys were investigated by XRD and SEM. The results show that the preferred orientation of α-Fe phase（200） crystals appears on the free surfaces of Fe86Zr5Nb1B8 and Fe86Zr1Nb5B8 alloys. With the increase of annealing temperature, the variations of average grain size of α-Fe phase from the free surface and wheel-contacted surface of Fe86Zr5Nb1B8 and Fe86Zr1Nb5B8 alloy are complex.
