摘要：
Nano-powders of Ti3Al and 2Al2O3 were synthesized from 3TiO2 and 5Al powders by high energy ball milling. Nanocrystalline Al2O3 reinforced composite was consolidated by high frequency induction heated sintering within 2 minutes from mechanochemically synthesized powders of 2Al2O3 and Ti3Al. The relative density of the composite was 99.5%. The average hardness and fracture toughness were 1340 kg/mm2 and 8 MPa·m1/2, respectively.
