| Abstract Scope |
Medium Mn low-density steels containing 5-10 wt.% Al exhibit interesting combinations of strength and reduced density for structural components. However, the hot rolled microstructures of these steels often contain large grains of δ-ferrite distributed in bands along the rolling direction and cube type textures, which can degrade strength and ductility. Some of these deleterious microstructural features may also remain after subsequent cold rolling and annealing. In this work, low-density steels were processed by asymmetric shear rolling to modify the microstructure through shear deformation, introduction of relatively high defect densities, grain refinement, and texture modification. The influence of asymmetric shear rolling on microstructural development and mechanical properties of low-density steels will be discussed. |
