Composites with Fe-based Ti+Ni3Al+Al2O3 addition were produced at 1000 degrees 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 Fe3Al, TiAl, NiAl, Al3Ni2, Al2O3 and Fe3O phases.en10.3989/revmetalm.178info:eu-repo/semantics/openAccessAl2O3Ball millingMicrohardnessNi3AlSinteringNi-AlMicrostructureNanocompositeStabilityArticle564Q4WOS:0006078112000012-s2.0-85099315883Q3
