TEXTURE EVOLUTION OF POLYCRYSTALLINE ALUMINUM DURING ROLLING DEFORMATION I. Experimental Study

Experimental investigations on rolling texture evolution in polycrystalline aluminum with initial randomly distributed texture and nearly cube texture were carried out via orientation distribution functions and orientation line analysis. The results show that the rolling textures for the sample with initial randomly distributed texture mainly consists of C, S and B components during rolling deformation while the orientation density values for the three textures only have slight difference, most crystallites aggregate along the alpha and beta orientations lines. The rolling texture for the sample with initial cube texture mainly consists of components C and S, while the orientation density value for B component is much lower than those for C and S components, most crystallites accumulate along the, beta fiber. The volume fraction for S texture component is much higher than those for C and B textures under the two cases.
