Texture Development of a Cold-rolled CuZnAl Alloy

In this paper, the textures of a CuZnAl alloy, produced d by cold rolling in the dual phase state, were studied. The alloy was heat-treated to obtain a microstructure of dual phases, then, cold-rolled with intermediate annealings. The pole figures of a and 3 phases were measured separately by the texture goniometer at the surface and center of rolled sheets. The orientation distribution function analysis showed that the a phase possessed a weak texture, and the 3 phase possessed a strong a-fiber texture. Compared the textures between the center and surface it was indicated that the textures were as a whole homogeneous. The formation of such two phase textures depended mainly on the volume percents of both phases as well as the recrystallization annealing.
