A field emission scanning electron microscope equipped with EBSD has been employed to evaluate the role of 0.013 wt% Nb on the evolution of the microstructure and texture of a novel thermomechanically processed low-alloy, medium-carbon steel. Specimens were subjected to hot-rolling with a total reduction of 80%, four passes in the recrystallization regime and four passes below the non-recrystallization temperature. Immediately after rolling, the strips were quenched to 420 °C and subsequently cooled slowly in a furnace to simulate strip coiling with transformation of austenite to bainite. The results showed that Nb microalloying results in a finer microstructure with a sharper texture when compared to an identical steel but without Nb. In addition, analysis of the retained austenite texture indicated that the main bcc texture components are the product transformed brass and copper components in the parent austenite.
