Microstructural analysis of hot steel ductility loss during its continuous casting

Abstract

The microstructure and metallurgy analysis of heterogeneous plastic deformation by unbending operation of CC product is included in present solution. Induced global deformation is localised in thin ferrite layers formed at austenite grain boundaries. This deformation is substantially higher than the global deformation. Futher, the conditions limiting the intensity of localised deformation are discussed. The reduction in heterogeneity deformation leads to the beneficial effect on the crack formation in CC steel products.
