Abstract

Nano-powders of 5Ni_0.6Fe_0.4 and Al₂O ₃ were synthesized from 3NiO and 2FeAl powders by high energy ball milling. Nanocrystalline 5Ni_0.6Fe_0.4-Al₂O ₃ composite was consolidated by pulsed current activated sintering method within 2 min from mechanically alloyed powders of Al₂O ₃ and 5Ni_0.6Fe_0.4. The average hardness and fracture toughness values obtained were 990 kg/mm² and 7.5 MPa.m _1/2, respectively.
