Abstract Scope Microalloying elements Ti and Nb are commonly added to high-strength steels as they can provide efficient means for additional strengthening due to grain refinement and precipitation strengthening mechanisms. In the form of solute elements or as nano-scaled carbonitride precipitates, Ti and Nb are also expected to have a significant effect on the microstructural changes during annealing. The present work investigates the separate influence of Ti and Nb on precipitation, ferrite recrystallization and austenite formation during annealing of various cold-rolled Dual Phase steel grades. Qualitative and quantitative data regarding these mechanisms are obtained by matrix dissolution techniques, SEM-FEG and TEM. Coupling models for non-isothermal precipitation, recrystallization and austenite formation allows obtaining good agreement to experimental results together with additional conclusions regarding the influence of microalloying elements. One of these conclusions is regarding the comparative effect of Ti and Nb in the form of solute elements and precipitates on delaying ferrite recrystallization.
