Abstract

Nano-powders of Ti₃Al and 2Al₂O₃ were synthesized from 3TiO₂ and 5Al powders by high energy bau milling. A nanocrystalline Al₂O₃ reinforced composite was consolidated by pulsed current activated sintering within 2 minutes from mechanochemicaUy synthesized powders Of Al₂O₃ and Ti ₃Al. Nanocrystalline materials, have received much attention as advanced engineering materials due to their improved physical and mechanical properties. The relative density of the composite was 99.5%. The average obtained hardness and fracture toughness values were 1510 kg/mm² and 9 MPa.m^1/2, respectively.
