摘要/Abstract

摘要： 研究了纵磁退火处理和张应力对1K101非晶合金薄带磁化特性以及损耗的影响,并采用Kerr方法观测了合金的磁畴形貌。结果表明,张应力驱动淬火态1K101合金感生出宏观单轴各向异性,使带材沿应力方向趋向于易磁化,且铁损下降,这与经纵磁退火处理后的带材磁化特征高度相似。通过磁畴观测发现,在张应力作用下,淬火态非晶合金中迷宫样窄小畴的磁畴壁沿应力方向呈Z字形排列,说明沿应力方向磁化时需消耗的外磁场能减少,这对带材软磁性能的优化起到了关键作用。

Abstract: Effects of longitudinal magnetic annealing and tensile stress on magnetic characteristics and loss of 1K101 amorphous alloy ribbon were investigated. Meanwhile, the magnetic domain morphologies of the alloy were also observed by Kerr method. The results show that macroscopic uniaxial anisotropy can be induced in the quenched 1K101 alloy by tensile stress, which makes the ribbon tend to be more easily magnetized along the stress direction, and the iron loss be decreased. These results are remarkably similar to the ribbon magnetization characteristics after the longitudinal magnetic annealing heat treatment. The magnetic domain observation shows that the original maze domains of the quenched alloy transform into Z-shape arrangement along the stress direction, indicating that the magnetic field energy consumed during magnetization reduces, which plays a key role in soft magnetic performance optimization.

Key words: 1K101 amorphous alloy, tensile stress, magnetic characteristics, iron loss, magnetic domain, anisotropy
