Description

technical field [0001] The invention relates to the field of metal materials, in particular to an iron-based amorphous alloy composite material. Background technique [0002] Iron-based amorphous and nanocrystalline alloys have excellent soft magnetic and mechanical properties, low price, and have broad application prospects in functional materials and structural engineering materials. However, its amorphous formation ability is still limited, and its saturation magnetization is lower than that of traditional silicon steel alloys. After annealing and crystallization, although the saturation magnetization and magnetic permeability are improved, the two crystallization temperature ranges of the alloy are too narrow, and the amorphous phase The low Curie temperature and the brittleness of the material after crystallization limit the high-temperature application of the material. In addition, iron-based amorphous alloys lack room temperature plasticity, and the material is prone...
