(1) The powder metallurgy technique can be used to produce pure aluminum Nano composite in which the nano
TiO2 particles are uniformly distributed within the matrix alloy with a low degree of porosity.
(2) Nano particles addition results in a significant improvement in, ultimate tensile and yield strength of composites.
(3) Hard Nano particles protect the surface, so the wear resistance is enhanced. It was found that the addition
of nanoparticles to the matrix alloy increases the hardness; as the nano TiO2 particles act as obstacles for the dislocation motion.
