| Abstract |
The formation of TiC and Al2O3 particles based on the self-combustion reaction of the Al-TiO2-CCuO 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℃ and thereafter was self-maintained, producing an Al matrix composite reinforced with thermodynamically stable TiC and Al2O3 particles. TiC and Al2O3 particles contributed to a considerable increase in the strength and stiffness, demonstrating the feasibility of this method as a practical application for structural parts. |
