摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a carburized sintered body for manufacturing the carburized sintered body of high strength efficiently.SOLUTION: The method of manufacturing the carburized sintered body includes: a molding step of molding raw material powder by pressure to obtain a molded body, the raw material powder obtained by adding Fe-Mn-Si-C powder that consists of an alloy or compound of Fe, Mn, and Si and C to iron alloy powder; and a carburizing step of heating the molded body in a carburizing atmosphere with a carburization temperature of 850-980°C to obtain the carburized sintered body that is a sintered body with a carburized layer formed near a surface thereof. The Fe-Mn-Si-C powder reduces and activates the particle surface of the iron alloy powder, and thereby a so-called sintering neck is formed between the particles of the iron alloy powder during the carburizing step. Therefore, both sintering of the molded body and the formation of the carburized layer are performed in the carburizing step without a sintering step. Thus, according to this manufacturing method, the carburized sintered body of high strength can be efficiently manufactured at low cost.
