Description

Texture (preferred grain orientation) characterization of polycrystalline aggregates has traditionally been done by X-ray or neutron diffraction techniques. These techniques are generally slow and destructive. Advances in ultrasonics over the last decade have made it possible to determine texture of cubic polycrystalline aggregates quickly and nondestructively [1–3]. It is known that all polycrystalline materials have some degrees of texture and, when texture is present, the materials are anisotropic, usually weakly orthotropic for rolled plates or sheets. The principle of ultrasonic characterization of texture is to infer texture by sensing and determining the material anisotropy.
