Abstract
The microstructure and mechanical properties of dense interpenetrating phase Al 2O 3–TiAl–Ti 3Al composites fabricated by pressure-assisted thermal explosion of TiO 2–Al powder blend have been studied. The unusual wavy morphology of aluminide–Al 2O 3 interface matching the lamellar γ–α 2 aluminide structure was formed due to big difference between oxygen solubility in γ and α 2. Crack deflection by alumina grains and crack bridging by the more ductile intermetallic may control the fracture toughness of these composites.
