Texture variations in an aluminum friction stir weld

The banding in a friction stir weld was determined to correspond to a periodic textural variation between the B / B ¯ component and a mixture of B / B ¯ and C components of the simple shear texture. These textures have similar deformation reference frames, indicating that the banding arises from a periodic variation in the strain magnitude or temperature during welding.
