SPED datasets for "Al-Cu intermetallic phase growth in hybrid metal extrusion & bonding welds exposed to isothermal annealing or direct current cycling"

SPED datasets from selected samples investigated for the Al-Cu HYB weld paper (https://doi.org/10.1016/j.matdes.2024.112867). Errors and omissions excepted. The .hspy and .mib files can be read using hyperspy. The SPED .mib file from the as-welded sample contains some scan artefacts from the data acquisition. This has been corrected for in the corresponding .hspy file. Two different alpha values were tested on the DC(-) samples.本数据集取自为撰写《Al-Cu HYB焊接》论文（https://doi.org/10.1016/j.matdes.2024.112867）所考察的精选试样，错漏除外。 可通过Hyperspy读取.hspy与.mib格式文件。 焊态试样对应的SPED（Scanning Precession Electron Diffraction）.mib文件中存在部分数据采集阶段引入的扫描伪影，该问题已在对应的.hspy文件中完成校正。 针对DC(-)试样，共测试了两种不同的α值。
