Structure of a Low Carbon Al-killed/Ti-added Steel

A low carbon Al-killed/Ti-added steel was processed in a Mexican steel company as a part of a research program which has the scope of developing ultra low carbon steels for automotive applications. Microstructural characterization of slab in the as-cast and re-heated conditions prior to the rolling operations is presented, giving emphasis to the nucleation of TiN on existing AlN particles, evidence of this behaviour is presented.
