Title

Segregation and Banding in Steel

Abstract

Steel with respect to its branding and segregation is discussed. The alloy can be segregated to either the dendrite core or to the interdendritic regions depending upon the liquidus and solidus lines of the phase diagram. The dendritic microstructure is partially broken down by plastic deformation, which causes the dendritic arms to be reoriented parallel to the rolling direction, in wrought materials. This creates the banded microstructures of ferrite and pearlite that are observed in plane carbon steels resulting from the segregation of manganese during solidification. Segregation of alloy can produce tremendous headaches with regard to controlling hardenability in steel. Microradiography can be used to detect segregation in steel. This technique relies on the elemental dependence of x-ray absorption.
