Composites with Fe-based Ti+Ni<sub>3</sub>Al+Al<sub>2</sub>O<sub>3</sub> addition were produced at 1000 °C sintering temperature for 1 h sintering time. The metallurgical properties of these composites were examined by scanning electron microscopy (SEM), optical microscopy (OM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and microhardness analyses. The final products produced by mechanical alloying were nanocrystalline nickel-rich solid solution and the size of average crystallite was in the range of a few nanometres. Titanium content in the reinforcement increased microhardness values of composite. The produced composites included Fe<sub>3</sub>Al, TiAl, NiAl, Al<sub>3</sub>Ni<sub>2</sub>, Al<sub>2</sub>O<sub>3</sub> and Fe<sub>3</sub>O phases.</p> ER -
