Effect of ARB process on textural evolution of AA1100 aluminum alloy

In the present work, commercial purity aluminum strips were highly strained up to an equivalent strain of 4.8 by the accumulative roll bonding (ARB) process at ambient temperature. Furthermore, the influence of the ARB process on the development of deformation texture at the quarter thickness of ARB-processed samples was considered. ARB process leads to the formation of strong orientation along the β-fiber and also to pronounced Dillamore and Copper components. It was found that textures which were formed at ARB-processed samples were almost the same for various ARB cycles and only their intensities differ. Also, the fraction of grains with sharp high angle boundaries increased when the number of ARB cycles increased.
