In this study, a method of judging the factors of penetration defects was established by using SEM and EPMA analysis. Penetration defects were made in a casting experiment with a mold in which the refractoriness was changed first. As for penetration defects which occurred due to physical factors, the boundary of the silica sand and metal was clear in the EPMA mapping. The EPMA mapping of the silica sand and the metal overlapped for penetration defects caused by chemical factos. In the interaction of factos, the EPMA mappings of silica sand and metal did not overlap but the silica sand had melted in the SEM image. Next, the penetration defects which occurred at the casting factory were analyzed by SEM and EPMA analysis, and compared with standard analysis data. As a result, penetration factors generated at the casting factory could be clarified.}, pages = {298--304}, title = {鉄鋳物に発生する焼付き欠陥の観察}, volume = {74}, year = {2002} }
