摘要：

The sintered steel made of a green compact of iron powder containing boron and sulfur and 1.4 mass% graphite consisted of ferrite microstructure and free carbon of more than 1.0 mass%. The X-ray diffraction analysis of the residue made by dissolving the sintered steel into nitric acid proved that free carbon had been graphitized. The graphite in the sintered steel orientated more strongly than the added graphite powder. The free graphite precipitated in the pore sites of the sintered steel on cooling after sintering.
