Nanopowder of TiCu was synthesized by high-energy ball milling. A dense nanostructured TiCu was consolidated using a pulsed-current activated sintering method within 1 minute from mechanically synthesized powders of TiCu and horizontally milled powders of Ti+Cu. The grain size and hardness of the TiCu sintered from horizontally milled Ti+Cu powders and high-energy ball-milled TiCu powder were 68 nm, 27 nm and 490 kg/mm², 600 kg/mm², respectively.

Nanocrystalline materials have received much attention as advanced engineering materials with improved physical and mechanical properties. As nanomaterials possess high strength, high hardness, excellent ductility and toughness, undoubtedly, more attention has been paid for the application of nanomaterials. Nanopowders of Al2O3, MgO and TiO2 were made by high energy ball milling. The simultaneous synthesis and sintering of a nanostructured MgTiO3-MgTi2O5-MgAl2O4 composite was investigated by the pulsed current heated sintering process. A highly dense nanostructured MgTiO3-MgTi2O5-MgAl2O4 composite was produced with simultaneous application of 80 MPa pressure and pulsed current within one min. The sintering behavior, gain size and mechanical properties of MgTiO3-MgTi2O5-MgAl2O4 composite were investigated. (Received December 11, 2012)

Nanopowder of FeAl and Al2O3 was synthesized from FeO and Al powders by high energy ball milling. Using the pulsed current activated sintering method, the nanocystalline Al2O3 reinforced FeAl composite was consolidated within two minutes from mechanically synthesized powders. The advantage of this process is that it allows very quick densification to near theoretical density and prohibits grain growth in nanostuctured materials. The grain size, sintering behavior and hardness of sintered FeAl-Al2O3 composite were investigated.

Nanopowders of Fe3N and Si were fabricated by high-energy ball milling. A dense nanostructured 12Fe-Si3N4 composite was simultaneously synthesized and consolidated using a high-frequency induction-heated sintering method for 2 minutes or less from mechanically activated powders of Fe3N and Si. Highly dense 12Fe-Si3N4 with a relative density of up to 99% was produced under simultaneous application of 80 MPa pressure and the induced current. The microstructure and mechanical properties of the composite were investigated.
