Abstract
Each stage in the production of metal sheet, i.e. casting, plastic working and heat treatment leads to the formation of preferred crystallographic orientation. The texture is an important (though not the exclusive) cause of anisotropy of physical properties, including plastic properties of metals and alloys. Anisotropy can be observed in metals submitted to some procedure. The anisotropy effects — permanent or transient — are easily found in every crystal. It may also be the consequence of the uniform distribution of the second phase, or impurities and segregation products following the plastic working. When the function defining the impact of internal stresses on a certain physical variable is not linear, it is possible that internal stresses cause anisotropy. Finally, the neighbouring crystals in a polycrystalline sample interact in the tension test; the effect of such interaction depends on their mutual crystallographic orientation.
