Influence of alloying elements on laser powder bed fusion processability of aluminum: A new insight into the oxidation tendency

This study focuses on the influence of alloying elements (Si and Mg) and the process parameters on the laser powder bed fusion (LPBF) processability of aluminum (Al). In this regard, pure Al, AlSi12, and AlSi10Mg parts with and without single tracks on their top surface were fabricated using a wide range of process parameters. The oxidation tendency, laser absorptivity, and powder attributes were evaluated to justify the densification level and …
