In this study, structural and mechanical properties of re-pressed and annealed iron (Fe)-alumina (Al2O3) metal matrix nanocomposites (MMNCs) was investigated. Composite composition with 5 wt.% of alumina to iron was fabricated using ball milling technique. Cylindrical sintered specimens were pressed at a load of 10, 12.5, and 15 kN in a die of similar diameter so as to have maximum deformation internally at grain as well as at grain boundary. These specimens were heat treated at 900, 1000, and 1100℃ for 1 h to anneal the stresses as well as to enhance the bonding between grains. Synthesized specimens were characterized for their microstructure, density and hardness respectively. Scanning electron microscopic images of the synthesized specimens revealed the formation of dense phase microstructure along with the presence of nano-dispersion of iron aluminate (FeAl2O4) phase. Secondary processing of metal matrix nanocomposites resulted in an increase in density of prepared specimens from 4.6960 to 5.5035 g/cm3 and the hardness values increased from 63 to 94 HRH.
