Abstract
In this study, the effect of solidification characteristics during layer-by-layer material deposition of an AlSi10Mg alloy through the height of a build is discussed. To characterize the microstructural features, transmission electron microscopy was employed. Of particular interest, a bar with 4 cm height, 2 cm width, and 1 cm thickness was additively manufactured through the laser powder bed fusion technique. Two samples were extracted from the bar, one close to the bottom and the other adjacent to the top of the sample. Comparing the two samples showed that the sample taken far away from the build plate revealed remarkable differences in size and morphology of the intermetallics and subgrains. This manifests a change in mechanical behavior moving from the bottom to the top of the build.
