Two filler materials (SiC and Al{sub 2}O{sub 3} particulate)-reinforced Al{sub 2}O{sub 3}/Al ceramic-matrix composites are formed by directed oxidation of a molten Al alloy. The process involves the directed oxidation reaction of a molten commercial Al alloy (Lanxide) with filler materials containing oxide additives (SiO{sub 2} and SnO{sub 2}) to yield an Al{sub 2}O{sub 3}/Al matrix material. Oxide additives are reduced to metal phases in the resultant matrix of composites and accelerate the oxidation process. Microstructures and phase constitutions of the composites fabricated with different filler materials and additives are presented. 7 refs.
