【摘要】 研究了F e73.5Cu1N b3S i13.5B9纳米晶软磁材料的磁导率温度稳定性、居里温度等特性以及退火温度对它们的影响。结果表明:退火温度低于520℃时,磁导率温度系数uα随环境温度的升高而提高;退火温度为540℃~580℃时,uα随环境温度的升高而降低,且在初始磁导率iμ-θ(温度)曲线上只出现一个Hopk inson峰;退火温度在520℃~560℃范围内,uα较小,磁性温度稳定性较高。更多还原

【Abstract】 Temperature stability of the magnetic permeability and Curie temperature trait which annealing temperature affected on nanocrystalline Fe_73.5Cu₁Nb₃Si_13.5B₉ alloy were investigated.The result shows that the temperature coefficient α_u increases along with annealing temperature enhancing when annealing temperature is less than 520℃,and α_u falls along with temperature and occurs only one Hopkinson apex on AC permeability vs temperature when annealing temperature is between 540℃ and 580℃.The temperature coefficient α_u is quite low when annealing temperature is between 520℃ and 560℃,so the magnetic stability of temperature is fine.更多还原
