• A356
• Aluminum matrix composites
• Nano titanium dioxide
• Ultrasonic treatment

The A356 aluminum matrix composites reinforced by different nano-sized titanium dioxide nanoparticles were prepared by semi-solid stirring and ultrasonic treatment. The mechanical properties and microstructure of the composites were tested. The experimental results show that TiO2 nanoparticles contribute to inhibit the formation of α-Al dendrite, refine eutectic silicon, and improve the mechanical properties of A356 aluminum alloy. Under the same mass percentage, the TiO2/A356 composite prepared by adding 1wt.% 40 nm titanium dioxide particles shows the best mechanical properties.
