Effects of direct-quenching and tempering on the microstructure and mechanical properties of an ultra-low carbon Ti containing bainite steel

Ultra-low carbon Ti containing bainite steel was prepared by multipoint dispersion supplying Ti wire in the melt, followed by controlled rolling, relaxation, direct-quenching (DQ), and tempering at temperatures in the range of 450 °C–700 °C. The evolution of microstructures under various heat treatm...
