The Fe-Ni compact bodies were fabricated using Fe-Ni mixed powders with 50 nm in diameter by injection molding process. The relationship between microstructure and material properties was characterized with respect to the volume ratio of powder/binder and sintering temperature with SEM and TEM. In the compact body having the volume percent ratio of 45(Fe-Ni) : 55(binder), which was sintered at the values of relative density and hardness were low about and 277.1 Hv, respectively. Using the composition of 50(Fe Ni) : 50(binder) and sintered at the values of relative density and hardness were respec-tively. The grain size of sintered bodies strongly depended on the sintering temperature. In both samples sintered at the average grain sizes were about 150 nm and 500 nm in diameter, respectively.
