摘　　要：采用单辊快淬法制备Fe40Co40Zr7V2B11和Fe40Co40Zr7V2B9Ta2两种非晶合金薄带,并对两种合金进行不同温度热处理。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:Fe40Co40Zr7V2B11合金的自由面存在α-Fe Co相(200)晶面择优取向,贴辊面为非晶结构;Fe40Co40Zr7V2B9Ta2合金的自由面和贴辊面均为非晶结构。两种合金自由面和贴辊面经不同温度退火后α-Fe Co相平均晶粒尺寸随退火温度的变化曲线完全不同。Fe40Co40Zr7V2B11and Fe40Co40Zr7V2B9Ta2 amorphous ribbons were prepared by single roller melt-spinning and after annealing at different temperatures.The microstructure of the samples was investigated by XRD and SEM. The results show that： for Fe40Co40Zr7V2B11 alloy, α-Fe Co crystals are strongly textured（200） on the free surface and the wheel-contacted surface shows amorphous structure; for Fe40Co40Zr7V2B9Ta2 alloy, both the free surface and the wheel-contacted surface show the amorphous structure. The grain size（α-Fe Co） curves of two alloys obtained from the free and wheel-contacted surfaces are very different after annealing at different temperatures.
