Abstract
A methodology is described to examine crystallographic textures in friction stir welds with respect to shear flow lines generated by a probe tool. For welds where deformation is dominated by the probe the textures are shown to be almost entirely the simple shear

in alternating bands across the whole weld. This suggests that the shear generated by the rotating probe is the dominant mechanism influencing microstructure/texture, with the tool forward motion having less influence.
