根据非晶态Fe_5Co_(73)Si_(10)B_(12)合金薄带不同方向磁化曲线与磁致伸缩曲线随退火状态的变化规律,发现Curie温度低于晶化温度的非晶态合金经旋转磁场热处理时,可以消除由于自发磁化场所感生的磁各向异性。初步分析和讨论了淬火态(制备)非晶态合金具有磁各向异性的原因。
Ribbon specimens were prepared from Fe_5Co_(73)Si_(10)B_(12) amorphous alloy and quenched, annealed or rotational field annealed separately. According to the variation on the magnetization and the magnetostriction figures with different annealed states of them, the magnetic anisotropy induced by the spontaneous magnetization field may be released by the rotational field annealing for such ahoy of which the Curie point is lower than the crystallizing temperature. Th ereason why the amorphous ahoy as-quenched is magnetic anisotropy has been analyzed and discussed.
