Stability of Crystallographic Orientations in Equal Channel Angular Extrusion of HCP materials: Application to Texture Analysis in Titanium

Abstract:

Article Preview

A numerical analysis of orientation stability is conducted for equal channel angular extrusion (ECAE) of hexagonal close-packed (hcp) materials based on lattice rotations from rate-sensitive crystal plasticity simulations. The relatively stable orientations associated with five slip modes are identified and then applied to interpret the characteristics of texture evolution in ECAE-processed titanium. The results indicate that during ECAE deformation, the slip plane and slip direction tend to rotate respectively towards the macroscopic simple shear plane and shear direction.
