This study investigates the impact of aluminum content on the deep drawability of interstitial free steels crucial for automotive applications. Using electron backscatter diffraction, it reveals a stronger ND <111> fiber texture in high-aluminum (High-Al) steels compared to low-aluminum (Low-Al) counterparts after full recrystallization. High-Al steels exhibit a higher Lankford parameter (rm) value, indicating improved formability. They also demonstrate faster recrystallization kinetics, attributed to rapid ND fiber grain nucleation. In contrast, Low-Al steels experience temporary strengthening during early recrystallization, hindering ND fiber grain nucleation. Precipitation studies show the absence of aluminum-containing precipitates in High-Al steels, while high-resolution secondary ion mass spectrometry imaging confirms elevated aluminum presence on specific grain boundaries. Molecular statics simulations reveal a decrease in grain boundary energy with aluminum addition, resulting in a system reaching a minimum energy state. Overall, this study underscores the pivotal role of aluminum in enhancing deep drawability through texture development, recrystallization kinetics, and grain boundary energy reduction in interstitial free steels.
