Abstract

Nanopowders of Fe, Al and $Fe_2O_3$ are fabricated by high energy ball milling. Using the pulsed current activated sintering method, the densification of nanocrystalline $Fe_2Al_5$ and $Al_2O_3$ reinforced $Fe_2Al_5$ composites were simultaneously synthesized and consolidated within two minutes from mechanically activated powders. The advantage of this process is that it allows very quick densification to near theoretical density and prohibition of grain growth in nanostuctured materials. 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 to the application of nanomaterials. Not only the hardness but also the fracture toughness of the $Fe_2Al_5-Al_2O_3$ composite was higher than that of monolithic $Fe_2Al_5$ due to the addition of the hard phase of $Al_2O_3$ and the crack deflection by $Al_2O_3$.
