The new concepts for building automotive structures with impact resistance, formability, and low specific weight lead to increase in the research for materials with high strength and toughness, combined with low density. The TWIP steel (Twinning Induced Plasticity) can meet these needs and therefore it is essential its development. The material of this work, 0.06C-25Mn-3Al-2Si-1Ni steel, with TWIP effect, was hot and cold rolled and then annealed at temperatures between 600°C and 850°C. The microstructural examination was focused in the recrystallization during annealing for different temperatures through optical and scanning electron microscopy (SEM). For mechanical evaluation tensile tests were performed. A polycrystalline model, based on micromechanics and working hardening theory, developed by Bouaziz et al., to predict the behavior of TWIP steels under tensile tests was applied to current steel. The results from the model are in good agreement.
