High-resolution electron-backscatter diffraction was used to study the effect of welding temperature on the microstructure, texture, and strength of friction-stir welded aluminum. In all cases, the grain structure development was shown to be primarily governed by continuous recrystallization, although discontinuous recrystallization may also play a role at relatively high temperatures. An increase in welding temperature was shown to lead to transformation of the morphology of the deformation-induced substructure from lamellar type to equiaxed type. This was deduced to alter strain compatibility requirements and thus change the texture from (Formula presented). to (Formula presented).
