Abstract Microstructure inhomogeneities between the core and the surface regions of cold rolled pure aluminum thin foils were documented and characterized by transmission electron microscopy. Different dislocation types were identified and these were recognized as responsible for the observed microstructure inhomogeneities. It resulted that as the foil thickness reduces to 10 µm the core region tends to form single grains decorated by few tangled dislocations, while the surface regions are characterized by cell and grain boundaries.

125 至 10 µm 厚的 5N-Al 箔中的趋肤效应

摘要 用透射电子显微镜记录并表征了冷轧纯铝薄箔的芯部和表面区域之间的微观结构不均匀性。确定了不同的位错类型，这些位错类型被认为是造成观察到的微观结构不均匀性的原因。结果是，当箔厚度减小到 10 µm 时，核心区域趋于形成由很少的缠结位错装饰的单个晶粒，而表面区域则以晶胞和晶界为特征。
