The FeSiAl fast quenching belt material was prepared by melt rapid quenching method, and the FeSiAl fast quenching belt material was flattened using a planetary high-energy ball mill. The effects of high energy ball milling and vacuum annealing on microwave electromagnetic parameters of FeSiAl......
Read More1.Amorphous nanocrystalline soft magnetic alloy [1] has been gradually becoming one of the research hotspots in the field of international strategic new materials due to its excellent properties such as high initial permeability (μi), low coercivity (Hc) and iron loss (Pc) [2-4], environmental......
Read More1. Effect of secondary transverse magnetic annealing temperature on phase structure of FeSiBCuNb alloy When the magnetic core undergoes conventional nitrogen annealing (NA) treatment or hot isostatic pressing, due to the residual stress caused by thermal shock and its own bending stress, the i......
Read MoreIron-based amorphous/nanocrystalline alloys have attracted the attention of researchers because of their excellent properties such as high saturation magnetic induction Bs, low coercive force Hc, high magnetic permeability μe, and low loss P. After decades of development, the comprehensive sof......
Read MoreMagnetic materials are ancient and widely used functional materials. The magnetic properties of materials were recognized and applied as early as 3000 years ago. For example, natural magnets were used as compasses in ancient China. Modern magnetic materials have been widely used in our lives, ......
Read MoreThe effect of salt bath nitriding on the properties of the permeable layer is mainly manifested in the hardness, wear resistance and corrosion resistance. In the hardness test, the orthogonal test method is developed according to reasonable process parameters, as shown in Table 2.2. The hardne......
Read MoreIn order to meet the low-loss requirements of large-capacity and high-frequency transformers for large-scale nanocrystalline iron cores, the heat treatment process of 50mm high nanocrystalline iron cores was explored, and two typical nanocrystalline alloys Fe73.5Cu1Nb3Si15.5B7 and Fe73.5Cu1Nb3......
