Abstract
A nanocrystalline 4Fe-Al2O3 composite was simultaneously synthesized and consolidated by a high frequency induction heated sintering method within 2 minutes from mechanically activated powders of Fe2O3 and 2FeAl. The average grain sizes of Fe and Al2O3 were 72 and 43 nm, respectively. The mechanical properties of the composite were investigated.

Keywords: Rapid Synthesis, Composite, Nanostructured composite, Mechanical properties, Fe-Al2O3.
