Microstructure analysis and metallographic observation show that the matrix is mainly black flake structure, and the inlay structure is composed of white block and black flake, And there are many white massive tissues far from the section area (, Further microhardness tests have proved that the white blocky structure is ferrite, and the black fine lamellar structure is troostite or a mixture of troostite and pearlite. The formation of large ferrite in the insert is similar to the formation of some phase change zones in the welding heat affected zone. Due to the metal hydrothermal effect in the casting process, this zone is in the two-phase zone of austenite and ferrite. The ferrite in this zone is fully grown, and its microstructure is maintained at room temperature. Because the bucket tooth wall is relatively thin, and the insert volume is large, the temperature of the central part of the insert is low, and no large ferrite is formed.
