Abstract

Nano-powders of 1.5TiAl and Al₂O₃ were synthesized from 1.5TiO₂ and 3.5Al powders by high energy ball milling. Nanocrystalline Al₂O₃ reinforced composite was consolidated by high frequency induction heated sintering within 2 min from mechanochemically synthesized powders of Al₂O₃ and 1.5TiAl. The relative density of the composite was 99%. The average hardness and fracture toughness values obtained were 1340kg/mm² and gMPa-ml _1/2, respectively.
