Abstract
Texture and anisotropy are persistent characteristics of polycrystal. Because of the ordered and periodic arrangement of atoms in crystal lattices, responses of each oriented crystals in a polycrystal to the same external forces are not similar. Crystal grains which are better accommodated to boundary conditions because of their energetically orientation stable, should have higher volume fractions. The dependence of crystal behaviors on their relative orientations to applied field vector(s) result in anisotropy. To enhance or reduce anisotropy, crystallographic texture in materials need to be controlled and improved.
