23 Heat Treatment Strategies for Optimizing the Mechanical Performance of a novel AlSi10Cu8Mg Alloy processed by PBF-LB
Laser-based powder bed fusion of metals (PBF-LB/M) for aluminum alloys enables the production of functional lightweight components; however, the portfolio of processable alloys is very limited due to their intrinsic poor processability, related to high reflectivity, high thermal conductivity, and susceptibility to cracking. Near-eutectic Al-Si alloys are widely used because their narrow solidification range improves processability. Nevertheless, alloy design strategies increasingly focus on novel compositions incorporating additional elements to improve thermal and mechanical performance. A representative example is AlSi10Cu8Mg, developed to exploit solid solution strengthening in the as-built condition and precipitation hardening through Al₂Cu formation upon heat treatment. While the alloy shows high strength and hardness, its ductility in the as built state appeared limited, and conventional T6 heat treatments are energy-intensive. This study proposes a tailored single-step thermal treatment, using either long, low-temperature aging or short, high-temperature aging to achieve an optimal balance between ductility and strength enabled by effective precipitate reorganization without excessive coarsening.
