Abstract The physical metallurgical characteristics of the titanium microalloyed strip produced by thin slab casting and rolling (TSCR) process, which include the precipitation of titanium containing compounds, matrix microstructure and strengthening mechanism, is briefly reviewed in this paper. It is shown that the precipitation of titanium occurs at various stages from thin slab casting to coiling. The ferrite grain size is gradually refined by the addition of titanium, but it will reach a limiting value when the titanium content is over 0.045%. Both the ferrite grain refinement and the nano-sized TiC precipitates can contribute to the increase in yield strength of the steel strip, and the latter is dominant when the titanium content is over 0.045%.
