Crystallographic texture is the only factor essentially influencing plastic anisotropy in annealed pure metals and single phase alloys. Therefore, the extreme states of anisotropy can be defined using the quantitatively evaluated texture. The macroisotropy condition in polycrystalline metals constitutes a limit which can be approached when diminishing the sharpness of texture. On the other hand perfect single crystal can be estimated as the opposite limit of plastic anisotropy. It has been shown that the deviation from the limiting state influences the mechanical behaviour of real single crystals and poly crystalline samples with a close-to-random orientation. This finding motivates the introduction of the notion of "texture" in real single crystals.
