Application of Ti Microalloying in a Thin-Slab-Cast Medium-Carbon Steel

• Addition of 0.035 wt.% Ti into a steel with 0.23 wt.% C and 1.3 wt.% Mn was designed to produce steels for axle housing application. The production of 11-mm-thick coils was carried out in a Direction Strip Production Complex strip mill. The present studies focus on structureproperties correlation of the steels as-rolled and after normalizing at 750°C. The precipitation, partial dissolution and re-precipitation behavior of TiC along with microstructure refinement in as-rolled steel and after normalizing are analyzed using electron microscopes. The results lay the foundation for application of Ti microalloying in heat-treated medium-carbon steels.
