Abstract

Nano-powders of Ti ₃Al and 2Al ₂O ₃ were synthesized from 3TiO ₂ and 5Al powders by high energy ball milling. Nanocrystalline Al ₂O ₃ reinforced composite was consolidated by high frequency induction heated sintering within 2 minutes from mechanochemically synthesized powders of 2Al ₂O ₃ and Ti ₃Al. The relative density of the composite was 99.5%. The average hardness and fracture toughness were 1340 kg/mm 2 and 8 MPam ^1/2 , respectively.
