摘　　要：利用X射线衍射和高分辨电镜对纳米γ-（Fe，Ni）合金颗位进行微观结构研究检测表明，颗粒主要由γ-（Fe，Ni）合金颗粒组成，其颗粒大小为10nm左右；X射线能增分析（EDS）表明，各个颗粒的Fe，Ni含量不相同，并给出颗粒含量分布图。用该种纳米γ-（Fe，Ni）合金颗粒作为吸波材料的吸收剂具有优异的微波吸收特性。Microstructure of γ-(Fe,Ni) alloy paricles has been investigated in terms of X-raydiffraction and (high resolution) electron-microscope. The results show that most of the particlesare γ-(Fe,Ni) alloy Particles and particle size is around 10nm. EDS (Energy Inspersive Spectrometer) analysis indicates that Fe or Ni contents vary with various particles. The Fe or Ni content distribution in the particles is given as well. The material has excellent microwve absorptivity withthe nanometer γ-(Fe,Ni) alloy particles used as microwave absorbents.
