چکیده انگلیسی


• Finite Element Method with implemented crystallographic model.
• Asymmetric rolling of polycrystalline titanium.
• Texture distribution across sample thickness.
• Internal stress distribution.
• Texture homogenization after asymmetric rolling.

The goal of the work was to study the asymmetric rolling process, especially the resulting textures formation, using the Finite Element Method (FEM) with implemented crystallographic deformation model. This implementation enabled the examination of deformation heterogeneity, taking into account the crystalline nature of the processed material. The asymmetric rolling process was also studied experimentally using the EBSD technique. Rolling asymmetry was realized using two identical rolls driven by independent motors, which ensured a controlled range of process asymmetry. We examined crystal deformation mechanisms, resulting texture and internal stress distribution in symmetrically and asymmetrically rolled polycrystalline titanium (grade 2). It was found that asymmetric rolling produces a homogeneous texture across the material thickness, contrary to symmetric rolling. The effects of texture modification, predicted in three sample layers, were compared with EBSD experimental results.
