Scanning electron diffraction tilt series data of an aluminium-steel interface region

This dataset contains scanning electron diffraction (SED) data used in the publication entitled "<strong>Microstructural and mechanical characterisation of a second generation hybrid metal extrusion &amp; bonding aluminium-steel butt joint</strong>". The data denoted “SED_HYB_...” were recorded from an aluminium-steel interface region that includes aluminium and steel grains, an interfacial Al-Fe-Si layer, and dispersoids and some oxide particles located within the aluminium region. The nanoscale interfacial intermetallic phase layer is polycrystalline, and to increase the probability of recording data from intermetallic phase crystals oriented close to zone axes, the data were recorded in a tilt series covering 30 degrees, in steps of 1 degree. The file names give the goniometer x-tilt values in degrees, e.g. " SED_HYB_TX-150.hdf5" denotes an x-tilt of -15.0 degrees. SED data recorded from an Au cross-grating specimen, named "SED_AuX.hdf5", and from a MoO3 specimen, named "SED_MoO3.hdf5", are also included for calibration purposes.本数据集包含用于发表于题为《第二代混合金属挤出与粘结铝-钢对接接头的微观结构与力学表征》的出版物中的扫描电子衍射（scanning electron diffraction，SED）数据。标注为“SED_HYB_……”的数据采集自铝-钢界面区域，该区域包含铝与钢晶粒、界面Al-Fe-Si层，以及分布于铝基体区域内的弥散相粒子与部分氧化物颗粒。该纳米级界面金属间相层为多晶结构，为提升采集到接近晶带轴取向的金属间相晶体衍射数据的概率，实验采用了覆盖30°、步长为1°的倾斜序列进行数据采集。文件名包含测角仪x轴倾斜角度信息（单位：度），例如“SED_HYB_TX-150.hdf5”实际代表x轴倾斜角度为-15.0°。此外，本数据集还包含用于校准的金交叉光栅试样（对应文件名为“SED_AuX.hdf5”）与三氧化钼（MoO3）试样（对应文件名为“SED_MoO3.hdf5”）的扫描电子衍射数据。
