Material Flow in Aluminum Friction Stir Welds

Article Preview

A detailed examination of the texture evolution occurring within a friction stir weld inAA2195 reveals features that are not consistent with current models of material ow in frictionstir welds. While the deposited weld is dominated by a B ideal shear texture component, thistexture periodically alternates with a B texture, indicating a reversal in the sense of the sheardeformation. In addition, the observed rotation of the orientation of these shear textures, andtheir replacement by a distinct, new shear texture orientation to correct for the misorientationthat develops, reveals a heretofore unobserved characteristic of friction stir welds that providesfurther details about material ow during friction stir welding.
