Graphite Cast Iron

ABSTRACTRemarkable elongations have been obtained on cast iron samples subjected to alternate thermal cycles around the A1 critical point, under a tensile stress lower than the yield stresses of the stable phases. This procedure makes use of the “phase transformation plasticity”, characterised by an apparent softening of the material during its structural evolution. The influence of the applied stress, as well as the heating and cooling rates,on the elongation per cycle has been studied. A quantitative comparison between this “soft” technique and the more classical high-temperature metal forming techniques (deformation in stable α or γ domains, or in α + γ domain, high temperature creep) showed that, for an equal strain, the internal cavitation resulting from the thermomechanical cycling deformation of spheroīdal graphite cast iron is much smaller than for other techniques. This soft technique leads to higher mechanical characteristics at room temperature.

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.
