| Abstract Scope |
Aluminum F357 (AlSi7Mg) is a versatile material used in aerospace and defense industries, which undergoes heat treatment for enhancing its mechanical properties. This study fabricated Aluminum F357 specimens using two different laser powder bed fusion systems and subjected them to five different heat treatments, followed by aging at two different temperatures for varying durations. The aged specimens were machined to create tensile specimens that were tested for mechanical properties. The study found that the specimens fabricated in the Z build direction had higher yield strengths than those subjected to HIP and unaged specimens. HIPed components when aged at 177°C for 1000 hours showed lower yield strengths. These results were consistent regardless of the fabrication system used, indicating the compatibility of the LPBF system fabrication. The study provides valuable information for the aerospace and defense industries to optimize their processes and produce high-quality components. |
