| Abstract Scope |
Aluminium containing ferritic low-density steels (F-LDS) have densities 12-15% lower than conventional steels, making them potential candidates for automotive applications. The present study is focused on recrystallization behavior, mechanical properties and their correlation with texture in hot/cold rolled and annealed samples of 6.8Al-Fe and 9.7Al-Fe (wt%) F-LDS. The XRD and EBSD techniques were used to evaluate the macrotexture and microtexture of the F-LDS. The ductility of hot and cold rolled material in both the steels was less than 2%, likely due to a high-volume fraction of brittle kappa-carbide. However, after cold rolling followed by annealing at 700 °C and 750 °C for 60 minutes, the fully recrystallized samples exhibited a dramatic improvement in ductility ranging from 22 to 35%. This improvement can be attributed to the development of a strong gamma-fibre texture ({111}<121>). Additionally, it is believed that cube and Goss texture also significantly influence the mechanical properties of F-LDS. |
