The efects of mechanical aloying conditions and the type of reducing agent on the solid state reductionof haematite have been investigated at room temperature. Aluminium titanium zinc and copper were used as reducing agent. Nanocomposites of metal-oxide in which oxide particles with nano size were dispersed in Fe matrix were obtained by mechanical alloying of with aluminium and titanium respectively However the reduction of by coppe was not occurred Composite materials of iron with and were obtained from the system of and after ball milling for 20 hrs and 30 hrs respectively. And the system of resulted in the formationof FeO with ZnO after ball milling of 120 hrs. The final grain sizes of iron estimated by X-ray diffraction line-width measurement were in the ranges of 24~33 nm.
