The evolution of texture and yield locus of AISI 409 ferritic stainless steel under different deformation paths was analyzed.Texture evolution with plastic deformation was predicted by two models: Taylor (TPG), assuming pencil glide in {hkl}〈111〉 slip systems and Viscoplastic under the relaxed constraint assumption (VRC), considering the following slip systems: {110}〈111〉, {112}〈111〉, and {123}〈111〉, selected according to a strain rate sensitivity law. TPG model tends to predict some stronger developments of texture than the VRC model.Predictions of stress–strain curves along different loading paths with TPG and VRC models were very close to experimental results. Texture evolution did not have a significant effect to modify the rate and the isotropy of the strain hardening process of AISI 409 ferritic stainless steel.

During forming, thickness reduction and thermal treatment affect the recrystallization and evolution of the crystallographic texture of metallic materials. The present study focuses on the consequences of rolling reduction of a widespread aluminum alloy with numerous automotive, marine and general-purpose applications, namely Al 5182. Emphasis is laid on the crystallographic texture and mechanical properties on both hot and cold-rolled semi-final products. In particular, a 2.8 mm-thick hot-rolled product was examined in the as-received condition, while two cold-rolled sheets, one 1.33 mm and the other 0.214 mm thick, both originating from the 2.8 mm material, were examined in both as-received and annealed (350 °C for 1 h) conditions. Electron back-scatter diffraction indicated the presence of a large percentage of random texture as well as a weak recrystallization texture for the hot-rolled product, whereas in the case of cold rolling the evolution of β-fiber texture was noted. In addition, tensile tests showed that both the anisotropy as well as the mechanical properties of the cold-rolled properties improved after annealing, being comparable to hot-rolled ones.
