Modification of Stress and Texture Distributions in Asymmetrically Rolled Titanium

Abstract:

Asymmetric rolling can be used in order to modify material properties and to decrease forces and torques applied during deformation. This geometry of deformation is relatively easy to implement on existing industrial rolling mills and it can provide large volumes of a material. The study of microstructure, crystallographic texture and residual stress in asymmetrically rolled titanium (grade 2) is presented in this work. The above characteristics were examined using EBSD technique and X-ray diffraction. The rolling asymmetry was realized using two identical rolls, driven by independent motors, rotating with different angular velocities w₁ and w₂. It was found that asymmetric rolling leads to microstructure refinement, texture homogenization and lowering of residual stress.
