| Abstract Scope |
Aluminum alloys are widely used owing to their high strength-to-weight ratio, high thermal and electrical conductivity, and inherent ductility derived from their face-centered cubic crystal structure. However, their performance under harsh operating conditions remains limited. This study investigates the effect of MoB ceramic particles on the laser powder bed fusion (LPBF) additive manufacturing of AlSi7Mg alloy metal matrix composites (MMCs). MoB ceramic particles with a size of 1-5 μm were mixed with pre-alloyed AlSi7Mg powder using a tumbler mixer. Both pure AlSi7Mg and AlSi7Mg/MoB MMC specimens were fabricated with LPBF. The as-printed AlSi7Mg/MoB exhibited superior mechanical properties and wear resistance compared to the as-printed pure AlSi7Mg. These findings highlight the potential of MoB-reinforced MMCs processed via LPBF to advance the performance of aluminum alloy components in defense, aerospace, and automotive applications. |
