A numerical analysis of orientation stability is conducted for equal channel angular extrusion (ECAE) of hexagonal close-packed (hep) 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。
