摘要 通过扫描电子显微镜-电子沟道图案（SEM-ECP）技术测定了快速凝固和随后退火的 Fe-6·5质量% Si合金带材中晶界的类型和频率，即所谓的晶界特征分布（GBCD）。在具有明确的{110}织构的完全退火带材中观察到高频的低角度边界和Σ3、Σ9、Σ11、Σ17和Σ19的重合边界。小角度晶界和重合晶界的总频率几乎占所有晶界的一半。更频繁出现的重合边界正是从立方晶体<110>旋转的重合取向理论上预测的那些，类似于之前在通过相同加工方法生产的相同合金的{100}织构带中观察到的边界。通过对不同纹理的丝带进行实验，证实了纹理类型与 GBCD 之间存在密切关系。
Abstract The type and frequency of grain boundaries, the so-called grain boundary character distribution (GBCD), has been determined in rapidly solidified and subsequently annealed Fe-6·5 mass% Si alloy ribbon by the scanning electron microscopy-electron channelling pattern (SEM-ECP) technique. High frequencies of low-angle boundaries and coincidence boundaries with Σ3, Σ9, Σ11, Σ17 and Σ19 were observed in a fully annealed ribbon with well defined {110} texture. The total frequency of low-angle boundaries and coincidence boundaries is almost one-half of all grain boundaries. The coincidence boundaries which occurred more frequently are exactly those predicted theoretically from the coincidence orientations for 〈110〉 rotation in cubic crystals, similar to those observed previously in {100} textured ribbons of the same alloy produced by the same processing method. The presence of a close relationship between the type of texture and GBCD has been confirmed by experiment on differently textured ribbons of th...
