摘要
利用真空退火,将非晶合金纳米晶化,并通过XRD试验手段验证了其纳米晶结构,研究了磁场退火对纳米晶合金软磁性能的影响。研究表明,在外加磁场条件下,对Fe_(74.5)Cu_1Nb_2Si_(13.5)B_9、(Fe_(0.5)Co_(0.5))_(73.5)Cu_1Nb_3Si_(13.5)B_9和Ni_(25)(Fe_(0.5)Co_(0.5))_(48.5)Cu_1Nb_3Si_(13.5)B_9纳米晶合金进行二次热处理,可以不同程度地减小合金的饱和磁致伸缩程度。然而,磁场退火后纳米晶合金在较低温度下的初始磁导率出现了不同程度的降低,原因可以归结为:在磁场退火的过程中,感生出的单轴各向异性增加了合金总的各项异性。
Influence of magnetic field annealing on soft magnetic properties of nanocrystalline Fe74.5 Cu1Nb2 Si13.5 B9, （ Fe0.5Co0.5） 73.5- Cu1Nb3Si13.5 B9 and Ni25（ Fe0.5 Co0.5） 48.5Cu1Nb3 Si13.5B9 alloys was investigated. In contrast to the nonmagnetic field annealing, the magnetic field annealing reduces As and remodels the μi-T curves of the samples in varying degrees. However, the value of μi decreases at relatively lower temperature, which is attributed to the increased effective magnetic anisotropy in the process of magnetic field annealing.
