Injection molded Fe sintered bodies were fabricated using two kinds of Fe powders which have an average size of 50 nm and a diameter of 3 μm, respectively. Using Fe powder of about 50 nm in diameter, comparatively dense bodies (94–97%) were obtained even at a low sintering temperature (600 °C–700 °C), whereas the Fe sintered body (1100 °C) using about 3 μm Fe powder showed relatively low density (about 93%). In the sintered bodies using 50 nm Fe powders, the grain size increased as the sintering temperature increased, but the values of hardness decreased. In the sample sintered at 650 °C, the values of relative density and grain size were 96% and 0.97 μm, respectively. The minimum value of wear depth was obtained due to the combination of fine grain size and comparatively high relative density.
