The possibilities of parameterization of microstructures such as SHG2, SHG4, SHG6, SHG10, SHG12, SHgd15, SHgd25, SHgd45, SHgd90, SHgd180, SHgd360 according to GOST (State All-union standard) 3443–87 based on the microstructures of cast iron with different diameter spheroidal graphite are shown. It is proposed to use the function of the density distribution of graphite inclusions in size for the classification of cast iron microstructures with spheroidal graphite. It is shown that density function of graphite inclusions can be used as a criterion of classification of microstructures of cast iron with spheroidal graphite, that offers new opportunities for the quantitative analysis of relations «microstructure-property» for cast iron with spheroidal graphite.

Color etching is a widely used technique for visualizing different phases in metallic materials. Its advantage to the traditional etching techniques is that it gives additional information within one phase, namely, the color shade of a given phase can change in a certain range. This paper demonstrates that, due to the physics of the color etching, the shade of a phase also depends on the crystallographic orientation of the investigated grain. As a test material, spheroidal graphite cast iron was used, and individual grain orientation was identified by automated electron back scattering diffraction (EBSD). Results showed that there is a strong correlation between grain orientation and the shades obtained by color etching.

Feasibility of semisolid forging of cast iron using rapid resistance heating was experimentally investigated. Gray pig iron FC250 and spheroidal graphite cast iron FCD600, whose carbon equivalents are both 4.3% in mass, were used for the experiments. Since these cast irons have a narrow semisolid temperature range, an AC power supply with an input electric energy control function was used. In this study, the resistance heating characteristics of the cast irons were firstly examined, and then their semisolid forging experiments were conducted. In the forging experiments, the conditions of the forgings such as microstructures and hardness properties were examined, and the feasibility of the semisolid forging of cast iron using resistance heating was discussed. As a result, it was found that the method presented here is highly feasible.
