Prediction of deformation and texture evolution in the vicinity of a hard particle in an FCC crystal
Plane strain compression of an FCC crystal of {011}<100> orientation containing hard particles was simulated using a finite element (FE) code based on viscoplastic crystal plasticity. The Goss orientation, {011}<100>, is stable during plane strain compression. Two-dimensional simulation shows that crystal orientation rotates around transverse direction (TD) in the vicinity of a particle. In two-dimensional simulation, plane strain condition does not hold strictly in the vicinity of a particle because of three-dimensional geometry of the particle. Three-dimensional simulation shows that orientation rotates not only around TD but also around rolling direction (RD). Combination of the rotation around TD, and RD results in complex rotation of orientation in the vicinity the particle. It is observed that the initial {011}<100> orientation rotates toward orientations of particle stimulated nucleation (PSN).
