    It is well known that the pore morphology has a direct effect on the strength of sintered material. On the other hand, the strength of sintered material is influenced by the microstructure. In this study, the effects of graphite powder diameter on the pore morphology and the microstructure of Fe-2%Cu-C sintered materials, where the graphite powder amount added was 0.6, 0.8 and 1.0mass%, were examined. The main results are as follows; (1) With decrease in the graphite powder diameter from 17 to 1.5μm, the pore size after sintering was reduced. (2) The tensile strength of sintered materials indicated a peak at 4.2μm of the graphite particle diameter. (3) The tensile strength was correlated to the area fraction of pearlite.
