In the accumulative roll bonding, two sheets of thickness t where one side of each is made slightly rough, are put together from the rough sides and rolled up. The rolling process should be such that the total thickness of two sheets placed on each other (t2) is reduced to the thickness t (i.e., the amount of deformation is equal to 50%). Anisotropy, is an important property of metal sheets which has a significant impact on the process in some forming modes. By performing one-axial tensile tests in three directions of rolling direction (RD), perpendicular to rolling direction (TD) and 〖45〗^oC with respect to rolling direction, how to change strength and percent elongation as well as the anisotropy in mechanical properties of sheet during various cycles of process is measured and investigated. The best mechanical properties were obtained in fifth pass where the tensile strength and elongation were 280 MPa and 18%, respectively. Also, by micro-hardness testing in the direction of sheet thickness, hardness changes in the thickness direction was studied where its value in the annealed sample was 39HV and increased to 68HV in the fifth pass. The metallography test was used to measure the grain sizes and to determine the physical and mechanical properties of the sample surfaces. By performing fractographic examination, we can better understand the cause of the fracture and the type of fracture, and finally, by performing X-ray diffraction spectrometry, we obtain pole figures of the material texture where the difference in anisotropy values can be justified by comparing them.
