.... Deviations from plane strain, either macroscopic (e.g., shear deformation at or near the surface of the sheet) or microscopic (e.g., as a result of the presence of second phases), will introduce other high stored energy orientations and therefore weaken the {111} nucleation texture. Conversely, oriented...
