Texture Analyses of Friction Stir Welded Single-phase Brass Using Electron Back Scattered Diffraction

Complex plastic deformation during friction stir welding causes variation of texture in different locations of the joint. Therefore, the as-acquired texture data from electron backscattered diffraction analysis are not often in the shear deformation frame of reference. In this study, the texture components of the friction stir welded single phase brass was studied. The results showed that the texture of the joint contained A_1^* (111)[1 ?1 ?2], A_2^* (111)[112 ? ], C{001}?110?, and Goss{011}?100? components. The existence of A_1^*, A_2^*, and C texture components revealed that the continuous dynamic recrystallization plays a dominant role in the microstructural evolution. In addition, the presence of Goss texture component showed that discontinues dynamic recrystallization may also participate in the new grain formation.
