Abstract

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.
