对Fe52Co34Hf7B6Cu1非晶合金进行了低频磁脉冲处理,研究低温真空退火对磁脉冲处理Fe52Co34Hf7B6Cu1非晶软磁性能的影响. 结果表明, 磁脉冲处理导致非晶合金发生纳米晶化,析出晶态相α-Fe(Co), 晶粒尺寸为5-10 nm, 形成的纳米晶粒弥散分布于非晶基体的双相纳米合金中. 对磁脉冲处理的试样进行低温真空退火,可以进一步优化纳米合金的软磁性能, 在100 ℃退火可以得到最佳的软磁性能.
The nanocrystalline Fe52Co34Hf7B6Cu1 soft magnatic alloys composed of bcc-Fe nanocrystals embedded in a residual amorphous matrix were obtained by the magneto-crystallization of melt-spun ribbons. In order to improve the soft magnetic properties of double--phase Fe(Co)--based nanocrystalline alloy, the nanocrystalline alloy specimens were vacuum annealed for 30 min at 100, 200 and 300 ℃. The results showed that the treatment of magnetic pulsing on the amorphous alloy resulted in the nanocrystallization, the grain size of precipitated α-Fe(Co) nanocrystallized phase was 5-10 nm. The low-temperature vacuum annealing of magnetic pulsed specimens further improved the soft magnetic properties of nanocrystalline alloy. The influence of annealing at 100 ℃ for 30 min on the properties is most obvious.
