Their attractive features are due to their isotropic property, small structural correlation dimension, and magnetic anisotropic constant. The interactive coupling between the 琢鄄iron (Fe) nanocrystalline phase and amorphous soft magnetic phase further reduces the magnetic anisotropy and magnetostrictive effect of the Fe鄄based amorphous and nanocrystalline composites. Therefore, Fe鄄based amorphous and nanocrystalline alloys have a high saturation flux density and high magnetic permeability, and have been widely applied for electric power, electronics, and information transmission and conversion industries. Now, Fe鄄based amorphous and nanocrystalline alloys have been produced and applied to various areas on a large scale. In this paper, the development histories, situation, and tend鄄 ency of Fe鄄based amorphous and nanocrystalline alloyswere briefly summarized. The research results of Fe鄄based bulk and ribbon amor鄄 phous alloys, along with nanocrystalline alloys with high saturation flux density (Bs ), were reviewed in detail. The main contents of this paper include the compositions and properties of high鄄Bs Fe鄄based bulk and ribbon amorphous alloys; the compositions, structure and properties of high鄄Bs Fe鄄based nanocrystalline alloys; and the effects of alloying elements on the magnetic properties. These results will provide valuable insights that can be used for the development of Fe鄄based soft magnetic materials with a high saturation flux density.
