摘要
观察了晶粒取向３％Ｓｉ－Ｆｅ在横向磁化场及横向拉应力作用下，磁畴结构和磁声发射强度的变化。在横向拉应力下，横向条状畴形成并增长。应力增大，横向条状畴碎化形成点状畴结构。磁畴与磁声发射强度变化相对应，揭示了磁场发射强度受横向拉应力影响的实质。
Changes are observed of oriented 3%Si-Fe in the magnetic domain structure and intensity of magnetic sound transmission under the influence of the transverse magnetic field and transverse drawing stress. A bar type traverse domain generates and grows up under the effect of the transverse drawing stress and it is broken into a dotted magnetic domain structure following the increase of Stress. The corrospondence of variation between the magnetic domain and intensity of the magnetic sound transmission reveals that the latter ls essentially influenced by the transverse drawing stress.
