Crystallographic Texture in Rolled Aluminum Plates: Neutron Pole Figure Measurements

In crystalline materials with anisotropic elastic constants, the propagation of ultrasound is strongly dependent upon crystallographic texture. This dependence may provide investigators with a relatively rapid and economical method for monitoring texture in processed materials such as rolled plate [1–3]. We have made use of ultrasound to characterize texture in rolled aluminum plates that are to be used in the fabrication of cans [4]. Ultimately, it would be desirable to incorporate ultrasound-based texture monitors in the manufacturing process so that texture can be automatically controlled.
