Study on Mechanical Properties of Al Metal Matrix Nanocomposites Processed Using Ultrasonic Vibration Available to Purchase

High intensity ultrasonic vibration was applied to disperse SiC nano-particles into molten A354 during solidification process to fabricate metal matrix nanocomposite (MMNCs). MMNCs: A354/SiC/1p was obtained by dispersing 1% SiC particles into the molten A354. The distribution of the nano-SiC particles in this material was investigated using scanning electron microscope. The mechanical properties of this nano composite were tested. A354/SiC/1p-T6 samples were also fabricated and tested. Mechanical properties of A354/SiC with different weight percentage of SiC particles were also investigated to find out the optimized content of particles. The results suggest that A354/SiC/0.5p-T6 with extra 15 minutes ultrasonic treatment has shown the highest mechanical properties.
