抄録
The microstructure of the dissimilar joint between the ductile cast iron (JIS-FCD400) and the carbon steel (JIS-S45C) was studied in order to clarify the behaviors of the carbon diffusion and the plastic deformation. The interface of the joint consists of four different areas with different microstructures: (i) spheroidized graphite with a similar diameter to the base metal of the cast iron; (ii) the multi phased structure consisting of ferrite, pearlite and spheroidized graphite; (iii) pearlite only; (iv) ferrite and pearlite structure which is similar to the base metal of the carbon steel. The analysis of the Si distribution, the zones (i), (ii) and (iii) were included in the cast iron and (iv) lied in the carbon steel. The formation mechanism of the these microstructures was explained by the diffusion of carbon from the cast iron to the carbon steel and the inhomogeneous distribution of temperature. The misorientation measurement by the electron backscattering diffraction clarified that the area near the interface, which is the boundary between (iii) and (iv), was exposed to plastic deformation.

The microstructure of the dissimilar joint between the ductile cast iron (JIS-FCD400) and the carbon steel (JIS-S45C) was studied in order to clarify the behaviors of the carbon diffusion and the plastic deformation. The interface of the joint consists of four different areas with different microstructures: (i) spheroidized graphite with a similar diameter to the base metal of the cast iron; (ii) the multi phased structure consisting of ferrite, pearlite and spheroidized graphite; (iii) pearlite only; (iv) ferrite and pearlite structure which is similar to the base metal of the carbon steel. The analysis of the Si distribution, the zones (i), (ii) and (iii) were included in the cast iron and (iv) lied in the carbon steel. The formation mechanism of the these microstructures was explained by the diffusion of carbon from the cast iron to the carbon steel and the inhomogeneous distribution of temperature. The misorientation measurement by the electron backscattering diffraction clarified that the area near the interface, which is the boundary between (iii) and (iv), was exposed to plastic deformation.
