Nano-powders of Fe0.67Cr0.33 and Al2O3 were synthesized from CrO3 and 2FeAl powders by high energy ball milling. A highly dense nanocrystalline 3Fe0.67Cr0.33-Al2O3 composite was consolidated by a pulsed current activated sintering (PCAS) method within 2 minutes from mechanically synthesized powders of Al2O3 and Fe0.67Cr0.33. The average hardness and fracture toughness values obtained were 840 kg/mm2 and 10 MPa·m1/2, respectively.
