在优化激光粉末床熔合工艺参数方面取得的最新进展导致了高致密化零件的出现。然而，这些参数的微小变化或使用再生粉末会导致次优零件，包含更多的缺陷。采用LPBF法制备AlSi10Mg试样，研究了工艺缺陷对AlSi10Mg试样的影响及其在拉伸载荷增加下的演变规律。这是通过采用原位微测试阶段结合高分辨率x射线微计算机断层扫描（XμCT）来实现的。这种组合方法在多个负载增量下提供三维（3D）图像。这些图像然后用于计算缺陷之间的内部应变在随后的加载阶段，并在本工作中报告。
The latest advances in optimising the process parameters of laser powder bed fusion (LPBF) result in high densification part. Nonetheless, slight variations of those parameters or the use of recycled powder leads to sub-optimal parts, containing more defects. AlSi10Mg samples were produced by LPBF using recycled powder to study the effect of process-induced defects and their evolution under increased tensile load. This is achieved by employing an in-situ micro testing stage combined with high-resolution X-ray micro computed tomography (XμCT). This combined approach provides three-dimensional (3D) images at multiple load increments. These images are then used to calculate the internal strains between defects in subsequent loading stages and are reported in this work.
