Abstract

Nano-powders of Ni and Al₂O₃ were synthesized from NiO and Al powders by high energy ball milling. The nanocrystaUine Al ₂O₃ - reinfored composite was consolidated by a pulsed current activated sintering(PCAS)) method within 2 minutes from mechanically synthesized powders of Al₂O₃ and 3Ni. The average hardness and fracture toughness values obtained were 690 kg/mm² and 6.1 MPa·m^1/2, respectively.
