Abstract

The formation of TiC and Al 2O 3 particles based on the self-combustion reaction of the Al-TiO 2-C-CuO system in an Al alloy melt was investigated. With an adequate amount of CuO in the system, a spontaneous reaction occurred within the Al alloy melt at 850°C and thereafter was self-maintained, producing an Al matrix composite reinforced with thermodynamically stable TiC and Al 2O 3Al 2O 3 particles. TiC and Al 2O 3 particles contributed to a considerable increase in the strength and stiffness, demonstrating the feasibility of this method as a practical application for structural parts.
