Abstract:
Additive Manufacturing (AM) stands out in lightweight construction, material efficiency and geometric freedom. But as it is still a relatively young technology only a small number of alloys has been developed and thus there is a lack of material diversity especially for highly stressed AM components.One way to increase mechanical properties is using composite alloys that are reinforced by ceramic particles.Subject of this investigation are the effects of reinforcing AlSi10Mg with different volume fractions of silicon carbide (SiC), by either mixing or milling and the processability of the reinforced powder in a LPBF process.The used powders are characterized including optical inspection, particle size distribution, particle morphology and flowability. The manufactured parts analyzed regarding the density and tested for their mechanical properties. Based on the results correlations between the powder manufacturing process, alloy composition and mechanical properties are evaluated.
