Intercritical Thermomechanical Treatments Applied to the Steel Heavy Plates
Keywords:
intercritical thermomechanical, microalloyed steel
Abstract
This paperwork shows the laboratory experiments made on X60 and X65 steels with several intercritical thermomechanical treatment applications. Two variants were used: "down-up" thermomechanical treatment with heating and rolling in the intercritical range and "up-down" thermomechanical treatment with preliminary complete austenitizing and rolling in the intercritic interval. High values of the strength characteristics and a good plasticity were obtained. A comparison was made with the obtained results of the classical thermal treatment application (normalizing).
