用原子力显微镜(AFM)观测不同外加张应力下540℃退火的Fe基合金薄带(Fe73.5Cu1Nb3Si13.5B9)断口形貌,结合X射线衍射谱和纵向驱动巨磁阻抗效应曲线,研究Fe基合金薄带张应力退火感生横向磁各向异性场过程中的应力作用机制.建立了包裹晶粒方向优势团聚模型,揭示了包裹晶粒方向优势团聚与磁各向异性场的关系.
The morphology of the Fe-based alloy strip (Fe73.5Cu1Nb3Si13.5B9) annealed at different applied tensile stress was observed by atomic force microscopy (AFM). Combined with the X-ray diffraction spectrum and the GMA-induced longitudinal magnetron effect curve, the Fe-based alloy The mechanism of stress in the process of transverse magnetic anisotropy induced by the annealing of the thin strip was established, and the grain orientation superior agglomeration model was established to reveal the relationship between the direction of grain agglomeration and the magnetic anisotropy field.
