采用焦耳热连续应力退火（CSA-JH）方法制备了磁导率可控、磁损耗低的铁基薄带。获得具有完全发展的各向异性的带所需的最短退火时间为1秒，但是为了获得具有小饱和磁致伸缩的充分结晶的带，需要进行长于2秒的退火。由具有受控磁导率和小饱和磁致伸缩的长带制备环形磁芯，并且在0.1-3 MHz的频率范围内评估磁芯的磁损耗和相对磁导率。磁导率保持恒定高达2 MHz，磁损耗低于具有类似磁导率值的其他类型的芯。这些结果表明，CSA-JH方法是实现具有优异磁性能的铁基磁芯的有前途的方法。(C)2008年由Elsevier B. V.出版。
We prepared an Fe-based ribbon with controlled permeability and low magnetic loss by continuous stress-annealing by joule heating (CSA-JH) method. The shortest annealing time necessary for the obtaining of the ribbons with completely developed anisotropy was 1 s, but in order to obtain the sufficiently crystallized ribbons with small saturation magnetostriction it is required to perform annealing longer than 2 s. A toroidal core was prepared from a long ribbon with controlled permeability and small saturation magnetostriction, and the magnetic loss and relative permeability of the core were evaluated in the frequency range of 0.1-3 MHz. The permeability was kept constant up to 2 MHz, and the magnetic loss is lower than that for other types of core with a similar permeability value. These results suggest that the CSA-JH method is a promising method for realizing an Fe-based core with excellent magnetic properties. (C) 2008 Published by Elsevier B.V.
