Obiettivo Centreline segregation occurs within continuously cast slab and this influences the type of the localised microstructure. Elements which are prone to segregate in structural steels include C, Mn, Si, P, S and Nb and an accurate measure of the segregation intensity can be obtained using electron probe microanalysis. It is known that such segregation can influence the fracture toughness together with other properties. There is growing concern among customers and regulating bodies that present specifications do not take sufficient account of this fact. It is, therefore, important that a quantitative relationship be established between the intensity of the segregating elements and the fracture toughness so that compositional adjustments to the parent plate can be made in order to optimise properties. Since it is not possible to obtain commercial samples of plate having controlled segregation characteristics it is intended to replace the central segregated region in commercial slab with inserts of known composition and thickness. It is also intended to carry out a limited assessment of the weldability of the segregated samples including the influence on the HAZ toughness.
