The cross-rolling is a new process that results in significant evolutions in microstructure of the metallic sheets. In this study, an aluminium 1050 sheet was rolled up to 95% reduction in cross directions for ten passes. The rolled samples were investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The rolled samples possess a high dislocation density and ultra-fine crystallite structure. In addition, an anisotropic texture was formed in the structure of material. In fact, the intensity of {220} planes of Al was extremely increased about 7500 counts per second (CPS) in cross-rolling process. In this research a new method called selected area electron diffraction (SAED) was used to determine the direction of planes. In cross-rolled samples, the rolling texture component {110} [001] was created that are known as brass texture (Bs). A regular geometric structure accompanied by ultrafine-grained observed in TEM micrographs. Ultra-fine crystalline structure is proved by rings which were obtained from SAEDs. The results show that the grain sizes are about 200 nm and 300 nm in cross-rolling and straight rolling, respectively.
