摘要：

The commercially pure Al matrix composites reinforced with micro-Ti (Ti) particles as well as micro-Al2O3 (MA) or nano-Al2O3 (NA) particles have been developed via powder metallurgy route. Detailed microstructural characterizations as well as evaluation of microhardness, wear and corrosion behaviour have been carried out. As a basis for comparison, the same has also been investigated for the Al composites reinforced with these particles alone (i.e., Ti, MA, NA). The hybrid composites (i.e., Al + Ti + MA and Al + Ti + NA) reinforced with two different types of particles (i.e., Ti + MA/NA) have been found to exhibit relatively better hardness response; higher wear resistance and inferior response to corrosion, as compared to the composites (Al + Ti, Al + MA and Al + NA) reinforced with these particle alone.
