摘要
对球磨后的FeSiAl合金粉末进行不同温度真空退火,并制备成软磁合金复合材料(SCM)。采用SEM、XRD和网络分析仪等分析手段,研究了退火后合金的相组成、超点阵结构有序度、平均晶粒尺寸和1MHz～1.5GHz的SCM的复磁导率,随退火温度变化的规律。结果表明:随着退火温度逐渐提高,DO3超点阵结构有序度由0.38增大到0.66、平均晶粒尺寸由36.93nm增大到71.41nm、SCM在同频率下的μ′和μ″均逐渐减小。
Ball-milled FeSiAl alloy powder was vacuum-annealed at different temperatures and was prepared to soft magnetic alloy composite material （SCM）. Using scanning electron microscopy, X-ray diffraction and network analyzer, the effects of annealing temperatures on the phase composition, ordering degree, the average grain size and the complex permeability of SCM within 1 MHz-1.5 GHz were studied for the FeSiAl alloy. With the increase of annealing temperature, the ordering degree of DO3 supedattice structure increases from 0.38 to 0.66, the average grain size increases from 36.93 nm to 71.41 nm, the real and imaginary parts of SCM＇s complex permeability at the same frequency decrease gradually.
