Ductile cast irons (DCIs) are of increasing importance in the renewable energy and transportation sectors. The distribution morphology graphite nodules, particular formation degenerate features during solidification, dictate mechanical performance DCIs. In situ high-speed synchrotron X-ray tomography was used to capture evolution nodules solidification DCI, including effect carbon concentration...

Ductile iron is a high-strength cast material. The spherical graphite obtained by inoculation treatment effectively improves the mechanical properties of iron, resulting in higher strength than carbon steel. However, severe corrosion may occur under specific circumstances, especially thermal water pipelines. In this paper, mechanisms at main defective points ductile were investigated using micr...
