This study investigates the mechanical properties of aluminum and aluminum 7075 alloy composites reinforced with titanium oxide (TiO2) and magnesium (Mg) nanoparticles. The fabrication process involved powder metallurgy techniques to achieve homogeneity and dispersion of the nanoparticles within the matrix. Various mechanical tests, including tensile, compression, and hardness tests, were conducted using Universal testing machine to evaluate the strength, ductility, and hardness of the composite materials. The results revealed enhancements in mechanical properties compared to the base materials, attributed to the synergistic effects of reinforcing phases. This study provides insights into the potential applications of these composite materials in aerospace, automotive, and other industries where lightweight, high-strength materials are required. Initial findings reveal that the addition of TiO2 and Mg particles significantly influences the mechanical behavior of both Al and Al 7075 alloy. The composites exhibit enhanced tensile and yield strengths compared to their respective base materials. Moreover, improvements in hardness and impact resistance are observed, indicating the potential for applications requiring structural integrity and durability.
