Stress Corrosion Cracking in Ex-service Gas Pipelines; A Comprehensive Study

The data presented was developed through analysis of EBSD datasets of SCC cracks taken from active low carbon steel pipelines. Samples were analysed on an FEI Inspect F50 SEM with an EDAX Hikari EBSD detector using OIM Data Collection 7 and analysed using OIM Analysis 7. Samples were obtained from the ND-TD plane to capture the morphology of the cracks and the resulting dataset rotated in software by 90 degrees about the TD direction to align the orientation of the sample to that of the system. The data contains information of grain boundary characteristics exported from standard OIM Analysis functions as well as some mechanical properties conducted on the sectioned steel samples.本数据集源自对取自在用低碳钢管道的应力腐蚀开裂（Stress Corrosion Cracking, SCC）裂纹的电子背散射衍射（Electron Backscatter Diffraction, EBSD）数据集的分析。样品采用FEI Inspect F50型扫描电子显微镜（Scanning Electron Microscope, SEM）搭载EDAX Hikari型EBSD探测器进行表征，测试过程使用OIM Data Collection 7软件采集数据，并通过OIM Analysis 7软件完成分析。样品取自ND-TD平面以获取裂纹形貌，后续通过软件将所得数据集绕TD方向旋转90度，使样品取向与系统坐标系保持一致。 本数据集包含从标准OIM分析功能导出的晶界特征信息，以及对截取样件测试得到的部分力学性能数据。
