Abstract: In this paper, the advantage of the ultrasonic full cavitation technique has been considered for the synthesis of metal matrix nanocomposites. The transmission electron micrographs show the uniform dispersion of the nano-alumina particles throughout the aluminium matrix. The use of vibrator and ultrasonic waves for the synthesis of nanocomposites does not give time to agglomerate the nano-alumina particles. The hardness results obtained from the micro indentation and the Vickers hardness tester show the similar values of 107 HV with a variation of ±14 HV. The hardness value obtained for different locations of the nanocomposites is much higher than the pure Al and bulk Al/Al2O3 composites. This confirms that the dispersion of nanoparticles throughout the Al gives rise to uniform hardness in the nanocomposites which is the advantage of the synthesis process, i.e., ultrasonic full cavitation technique.
