【Abstract】 The iron Buddha in Fuzhou Kaiyuan Temple is one of the biggest ancient ones, existing both at home and abroad.In this paper, the construction of cast object, the state of inner surface, the chaplets with their affected zones, the gridding stripes, the metallographic structure, and the chemical composition were exhaustively characterized. The observation illustrated that there was no any sign of cold steam existed in the main structure of the iron Buddha.The chemical calculation exhibited that the carbon equivalent is 4.3%, falls into eutectic composition. The metallographic analysis displayed that there is white cast iron on the surface, but mottled cast iron in the substrate.We try to discuss the advantages, causes and related technologies of the three important technological characteristics observed.更多还原
