The powder sizes of Fe and ZrO2 were 70 nm and 12 nm, respectively. Highly dense nanostructured 4/3Fe-ZrO2 composite was consolidated by a pulsed current activated sintering method within 1 minute from the mechanically synthesized powders (Fe-ZrO2) and horizontal milled Fe2O3+Zr powders under the 1 GPa pressure. The grain sizes of Fe and ZrO2 in the composite were calculated. The average hardness and fracture toughness values of nanostuctured 4/3Fe-ZrO2 composite were investigated.
