Mechanical Properties of Dendritic and Inter-Dendritic Regions in As-Cast Medium-Carbon Steel

Abstract:

During solidification of steel, dendrite nucleation and growth leads to the segregation of alloying elements in the inter-dendritic regions. The dendrite arms are low in carbon while alloying elements segregate to the inter-dendritic regions. During subsequent hot-rolling, this variation in alloying element content leads to the formation of regions of high and low solute content, which in turn, leads to the formation of microstructural banding during heat treatment. In the present study, the respective mechanical properties of these dendritic and inter-dendritic regions were studied in medium carbon steel in order to investigate the rotation of dendrites during hot rolling.
