Abstract: The effect of strong shear on the micro-deformation behavior and crystal rotation evolution of rolling single layer crystal foil was deeply analyzed in order to determine the optimal foil rolling process. A crystal plastic finite element model based on dislocation slip mechanism was used for simulation, and the maximum differential speed ratio reached 1.5. A single layer crystal foil rolling model with random grain orientation was established to investigate the grain boundary interaction characteristics of oligocrystalline microstructure. The results show that the micro-deformation and crystal rotation are significantly localized by strong shear. The shear deformation of grain is promoted by strong shear and the coordinated deformation capacity of grain boundary is enhanced. The slip is more concentrated and anisotropic because of initiated slip can be extended and the main slip band shrinks and disperses to form a new secondary slip band by the shear deformation which is strengthened in the rol-ling zone. After foil rolling, the grain orientation mainly rotates and disperses around the width of the foil. The rotation angle increases and the dispersion point becomes more concentrated and stable by strong shear. The simulation results show that the anisotropy of single layer crystal foil rolling deformation is seriously affected by strong shearing, which leads to preferred orientation, slip localization and non-uniform stress-strain distribution.
