| Abstract Scope |
The AlSi10Mg alloy has garnered significant interest for its utilization in L-PBF, primarily due to its inherent lightweight nature and exceptional property via L-PBF. However, the limited elongation and relatively low production rates associated with L-PBF constitute major impediments to the widespread industrial adoption of AlSi10Mg components. Furthermore, while L-PBF-processed AlSi10Mg exhibits outstanding mechanical properties, these often surpass the target specifications for parts traditionally manufactured through casting. To address these limitations, this study investigated the effects of key process variables and heat-treatment-related variables on the forming speed and final mechanical properties of AlSi10Mg. The findings of this research demonstrate the successful attainment of customized mechanical properties in L-PBF AlSi10Mg that align with automotive-part requirements, alongside a substantial improvement in the build rate. Notably, the L-PBF-processed AlSi10Mg met the durability specifications established for automotive prototypes. This approach holds the potential for significant cost reductions while preserving acceptable mechanical performance for automotive-industry. |
