摘　　要：在备有拉伸装置的JEM-200CX透射电镜下对Fe-Cr-Al系铁磁性阻尼合金中铁素体内的磁畴结构及畴壁运动进行了动态观察。观察结果表明:磁畴在外力作用下的运动是通过部分原畴壁的消失,新畴壁的形成以及新、旧畴壁的重构来完成的,本文还初步探讨了铁素体内磁畴运动的规律。The Dynamic observation of magnetic domain structure and movement of domain wall within ferrite in Fe-Cr-Al series ferromagnetic damping alloys was made by the in-situ technique in JEM-200CX TEM equipped with tensile platform. The observation showed that the movement of magnetic domain under external stress accomplished through the disappearance of part prior domain walls, formation of new domain walls and reconstruction of prior and new domain walls. The characteristics of magnetic domain movement wishin ferrite were preliminary researched.
