摘要

软磁材料具有低矫顽力和高磁导率的特点。近年来,利用非晶合金退火获得的纳米晶合金引起了人们的广泛关注,因为几十纳米的小晶粒尺寸的纳米晶合金具有与非晶合金相当的低矫顽力场。由于纳米晶软磁材料通过控制晶粒尺寸来获得优异的软磁性能,因此晶粒的微观结构对材料的软磁性能有重要影响。在这项研究中,我们测试了Fe-Si-B-P-Cu纳米晶软磁合金的磁性能。在结晶过程中,观察结果揭示了生成的微结构与软磁性能之间的相关性。

Magnetization controlled by crystallization in soft magnetic Fe-Si-B-P-Cu alloys.

Soft magnetic materials have low coercive fields and high permeability. Recently, nanocrystalline alloys obtained using annealing amorphous alloys have attracted much interest since nanocrystalline alloys with small grain sizes of tens of nanometers exhibit low coercive fields comparable to that of amorphous alloys. Since nanocrystalline soft magnetic materials attain remarkable soft magnetic properties by controlling the grain size, the crystal grains' microstructure has a substantial influence on the soft magnetic properties. In this research, we examined the magnetic properties of Fe-Si-B-P-Cu nanocrystalline soft magnetic alloys obtained by annealing amorphous alloys. During crystallization, the observation findings reveal the correlation between the generated microstructures and soft magnetic properties.
