The mechanical properties of engineering materials are directly controlled by the underlying microstructure, which in turn is governed by the processing methods. The relevant details of the microstructure that influence strongly the elastic-plastic properties of the material include the lattice orientation distribution (texture), the grain size and shape distribution, and the arrangement and distribution of dislocation networks on the various slip systems in the constituent crystals. Of these, the crystallographic texture is perhaps the most important aspect of microstructure that has a strong influence on the elastic and the initial yield properties of most polycrystalline materials used in the manufacture of engineering components. It should also be noted that crystallographic texture is likely to have the dominant effect on the inherent anisotropy exhibited by these materials.
