をもつようになるという知見を得たのである。Therefore, from the above-mentioned viewpoint, the present inventors conducted research to produce a carbide-dispersed Fe-based sintered alloy with finer carbides. During production, if Ni-Mn alloy powder containing 40 to 80% Mn is used instead of Fe-P alloy powder used as raw material powder, the growth of carbides is suppressed, and in fact, this is caused to become finer. This led to the discovery that the resulting carbide-dispersed Fe-based sintered alloy has excellent wear resistance.
