A three-dimensional crystal plasticity finite element method model is developed to investigate the influence of the grain boundary (GB) misorientation on the equal-channel angular pressing deformation of aluminum bicrystals. Aluminum bicrystals with symmetric 〈112〉 tilt boundaries and misorientation...
