Abstract: The electron beam melting (EBM) process enables the production of complex designs, enhances metallurgical bonding, and minimizes material waste. However, challenges such as non-uniform particle dispersion, unwanted brittle phase formation, and particle clustering during high-temperature processing can negatively impact the mechanical properties of composites. Present research addresses the research gap and enriches the functional properties of aluminum alloy (AlSi10Mg) composites developed with varied wt.% of titanium boride nanoparticles (TiB2) via EBM process under conditions of 1.2 kW beam power, a high scanning speed of 2000 mm/s, and a build temperature of 750 °C. To improve particle stability and prevent boron decomposition, 0.5% zirconium is also added during the process. The synthesized AlSi10Mg alloy with varying concentrations of TiB2 is subjected to an annealing process. The study investigates the effect of TiB2 nanoparticle concentrations on the functional properties of AlSi10Mg nanocomposites. Transmission electron microscope (TEM) analysis reveals a uniform dispersion of particles without clustering, indicating limited porosity. The AlSi10Mg alloy, processed with 3 wt.% TiB2 nanoparticles, exhibits a reduced grain size of 9 μm. This alloy exhibits optimal tensile strength and impact strength, along with an increase in Vickers hardness that is 71%, 27%, and 65% higher than the standard AlSi10Mg alloy. Based on these findings, the AlSi10Mg alloy combined with 3 wt.% TiB2 nanocomposite shows significant potential for lightweight structural applications in the automotive industry.
