Al₂O₃/5 vol%Ni nanocomposite materials were fabricated by pulse electric current sintering (PECS) to achieve suitable microstructures. Their mechanical and magnetic properties were investigated and related to microstructure developments. Rapid densification of nanocomposites and various microstructures was accomplished by controlling PECS temperatures. Microstructures affected mechanical properties such as fracture strength, fracture toughness and hardness. Mechanical properties of Al₂O₃ were improved by Ni; fine dispersion into Al₂O₃ matrix improves changes in various ferromagnetic properties.
