In the previous report, it was confirmed that the precipitation of carbide M_<23>C_6 can be occurred at the boundaries between austenite and ferrite grains. With the use of various means such as optical and electron microscopes, electron diffraction, and the state analysis of the extracted residues by X-ray diffraction, the examination was carried out at which niobium added can be detected. It was confirmed that the massive carbides of niobium (NbC) having f.c.c. structure precipitated at the boundary between austenite and ferrite grains. From the ion micro-analysis (IMA) of the extracted residues, molecular ions of iron, chromium, molybdenum, nitrogen, and oxygen were detected.
