| 摘 要： | 采用单辊快淬法制备Fe81Zr5Nb4B10非晶合金带,并在不同温度下对其进行退火处理,利用XRD和振动样品磁强计(VSM)测试了合金自由面和贴辊面的结构及磁性能。结果表明:随着退火温度的增加,淬态合金由完全的非晶态结构转变为非晶与纳米晶的混合结构,晶粒尺寸、晶化体积分数增大,晶粒间的非晶层厚度减小。和自由面相比,贴辊面的晶粒尺寸较大,晶化体积分数较小,晶粒间的非晶层厚度较大。合金的矫顽力和比饱和磁化强度σs随着退火温度的升高逐渐增大。

| Abstract: | Fe81Zr5Nb4B10 amorphous ribbons were prepared by the single roller melt-spinning process and annealed at different temperatures. The Fe81Zr5Nb4B10 alloys structure of free side and contact side were studied by XRD, and the magnetic properties of elevated temperatures were investigated by vibrating sample magnetometer (VSM). The results showed that with the increase of annealing temperature, Fe81Zr5Nb4B11 as-quenched amorphous alloy transited from a completely amorphous structure into a mixed structure of amorphous and nanocrystalline. Grain sizes and crystallization volume fraction increased, while the amorphous layer between grains decreased. Compared with free side, the grain sizes and the amorphous layer between grains of contact side were bigger, crystallization volume fraction was smaller. Coercivity and special saturation magnetization increased gradually with the increase of annealing temperature. |
