摘要：

In the present work, the accumulative roll bonding process was carried out on a 7005 aluminum alloy sheet to six passes. The microstructure and texture evolution was investigated by transmission electron microscope, electron backscatter diffraction analysis, and x-ray texture goniometer. With the increase of ARB passes, the microstructure was refined and the fraction of high angle boundaries increased. The hardness of different ARB process specimens was measured and showed that as the ARB passes increased, the hardness rose obviously. The tensile strength of 6 passes reaches 423.4 MPa and the elongation is 4.6%. The material is strongly textured where individual layers possess typical FCC rolling texture components and the variation of each texture is different. This is attributed to the microstructure evolution during the ARB process.
