• Resumen

  • Advance High Strength Steels (AHSS) have been widely used in the automotive industry during the last decades due to their excellent combination of strength and ductility and competitive cost. Current investigations focus on the development of a 3rd generation of AHSS with higher levels of strength and ductility and excellent formability while maintaining a competitive cost. This goal can be achieved by microstructural optimization through an appropriate thermomechanical treatment and chemical composition design. In this work, the effect of deformation and alloying elements on the continuous cooling phase transformations and final microstructures after different thermomechanical and heat treatments has been studied using different experimental techniques in three advance high strength steels microalloyed with Ti-Nb, Ti-Nb-Mo and Ti-Nb-Mo-V.
