Core segregation at an untreated steel out of 1.2210
Segregations arises during the solidification of the steel, at the transition the phase from the liquid in the solid condition. Alloying elements and inclusions are enriched in the segregations. Positive and negative areas are existing in a segregation. The segregation distribution is dependent on different factors which positively or negatively influence the form. These factors are the casting temperature, casting rate, stirring parameter and cooling rate. Cementite as a lattice on the grain boundaries is the hypereutectoid part of carbon in the form of Fe3C. The higher the carbon content is, the stronger the lattice usually is, too. This particularly makes himself noticeable inside the core segregations.
