    Abstract

    For strengthening of Fe-Cu-C sintered material including inexpensive graphite particle the pore size needed to decrease. For this purpose, graphite powder amount was altered 0.6,0.8 and 1.0mass%, and the average diameter was changed in 1.5,4, 10μm. The present study is examined tensile behavior. As the result, the pore size decreased with the graphite particle diameter. Meanwhile, tensile strength indicated a peak at 4pm of the graphite particle diameter. This phenomenon was corresponded to pearlite area fraction. We guessed to be controlled the diffusion of Cu to Fe particle was a main factor.
