Ben Amir et al.

Summary: This study investigated the effects of the hot-build platform and post-processing stress relief treatment on the mechanical properties and microstructure of an AlSi10Mg alloy manufactured by selective laser melting. The research found that the distance from the heated build platform influenced surface hardness, dynamic performance, and relative density, while the stress relief treatment resulted in significant softening in mechanical properties. By correlating these findings to various fundamental characteristics, the study provided insight into the competing strengthening mechanisms activated during the fabrication process.
