| Abstract Scope |
Additive manufacturing of Al alloys presents an opportunity to produce complex parts that leverage their high specific strength. The feasibility of using AlSi10Mg in laser directed energy deposition (L-DED) has not been widely studied. Therefore, this paper aims to study the effect of processing parameters on the fabrication of single-tracks, thin walls and blocks using AlSi10Mg powder in L-DED. Thin walls and single-tracks depositions were used as a guideline to deposit blocks. Blocks were deposited using L-DED, and the physical, microstructural, and mechanical properties of the samples were investigated. Results demonstrated that the morphology of the single tracks did not dictate the morphology of the bulk samples and care must be taken when transitioning from depositing single tracks to bulk samples. Results from microhardness and tensile tests show anisotropy along the build direction for elongation and ultimate tensile strength. Microhardness and yield strength, however, were mostly uniform throughout the build. |
