Texture evolution in commercially pure titanium after warm equal channel angular extrusion
چکیده انگلیسی

Texture development in commercially pure titanium during equal channel angular extrusion (ECAE) through Routes A, Bc and C has been studied up to three passes at 400 °C. Textures were measured using X-ray diffraction, while the microstructural analyses were performed using electron back-scattered diffraction as well as transmission electron microscopy. Occurrences of dynamic restoration processes (recovery and recrystallization) were clearly noticed at all levels of deformations. Finally, the textures were simulated using a viscoplastic polycrystal self-consistent (VPSC) model. Simulations were performed incorporating basal, prismatic and pyramidal slip systems as well as tensile and compressive twinning. The simulated textures corroborate well with experimental textures in spite of the occurrence of dynamic restoration processes.
