Abstract
An additively manufactured titanium alloy sample has been characterized by X-ray computed tomography and optical microscopy serial sectioning to enable a correlative analysis of internal porosity. Titanium alloy ball bearings were adhered to the surface of the cylindrical sample to aid the registration of the datasets. The characterization data includes five X-ray computed tomography scans from four different instruments and optical microscopy serial sectioning images. The methods and parameters used for collecting these multiple datasets, and reconstructed data for each dataset‘s selected volume of interest are provided. Raw projection data from each computed tomography scan are also offered. Unanticipated artifacts within the serial sectioning experiment are highlighted, and the potential impact of these artifacts is discussed.
通过 X 射线计算机断层扫描和光学显微镜连续切片对添加制造的钛合金样品进行了表征，以便对内部孔隙率进行相关分析。钛合金球轴承被粘附在圆柱形样品的表面，以帮助数据集的登记。表征数据包括来自四种不同仪器的五次 X 射线计算机断层扫描和光学显微镜连续切片图像。本文提供了收集这些多个数据集的方法和参数，以及每个数据集所选感兴趣体积的重建数据。此外，还提供了每次计算机断层扫描的原始投影数据。重点介绍了序列切片实验中的意外伪影，并讨论了这些伪影的潜在影响。
