The texture of polycrystalline wires and sheets

Abstract

Metals, minerals and other polycrystalline substances which have undergone severe deformation in engineering processes display varying amounts of preferred orientation. The term ‘preferred orientation of texture’ is used to describe a certain alignment of crystallographic planes and directions in a preferred manner with respect to the direction of maximum deformation. Preferred orientation is also present in solidification processes, particularly when dendritic growth conditions are maintained. When the preferred orientation is a result of deformation, it is very dependent on the slip and twinning systems in the metal; but when orientation results from solidification, it depends mainly on the crystal structure.
