Thermomechanical Processing has been successfully applied in the hot mill since about 1970. Its attractiveness comes from its ability to control the strength and toughness of structural grades in a efficient, continuous process, based mainly on control of microstructure. This research has shown that variations in the stored energy of the cold band going into the CGL anneal can drastically alter the final microstructure and properties of high strength dual-phase steel. This stored energy is influenced by the composition, especially microalloying, the processing of the hot band coils and by the degree of cold reduction. In this study, the changes in microstructure were characterized by OM, SEM, HRTEM and EBSD(IQ, KAM, Stored Energy and grain boundary analysis). The hardness, tensile and hole expansion properties were also determined. These experiments, results and implications will be presented and discussed.
