1EFFECT OF Si CONTENT ON ORDERING DEGREE AND ELECTROMAGNETIC CHARACTERISTICS IN FeSiAl ALLOYS显示文摘FeSiAl alloys ribbons synthesized by melt-quench were annealed in vacuum at 873 K for 60 min.The flaky powders were prepared by milling the annealed ribbons for 70 h.After milling,the powders were heat treated at 573 K for 90 min.The order- ing degree of the powders lattice structure was analyzed by X-ray diffraction (XRD). The measurement of specific saturation magnetization was carried out by vibrating samples magnetometer (VSM).Complex permittivity and complex permeability in the frequency band of 0.5-18 GHz were measured with the vector network analyzer.The ordering degree of the superlattice structure increased from 0.27 to 0.49.Complex permittivity and complex permeability decreased with increasing Si content.After or- dering,the specific saturation magnetization decreased from 134.2 to 85.0 A·m^2·kg^(-1). For use in anti-EMI material,the total contents of Si and Al in FeSiAl alloys should be controlled at a low level.T.D. Zhou L.J. Deng D.F.
