Research of textures of ultrafine grains pure copper produced by accumulative roll-bonding
چکیده انگلیسی

Deformation textures and recrystallization textures of ultrafine grains pure copper produced by asymmetrical accumulative roll-bonding (AARB) and symmetrical accumulative roll-bonding (ARB) respectively were investigated using X-ray diffraction (XRD). It was found that dominant deformation textures of copper after 98.4% strain are {1 0 0}<1 1 0> shear texture by AARB and {2 1 1}<1 1 1> copper texture by ARB, a mixed “deformation–recrystallization” texture is observed during the first stage of recrystallization, dominant recrystallization texture is {0 0 1}<1 0 0>cube texture in samples produced respectively by AARB and ARB. We suggest that deformation textures and recrystallization textures are controlled by the crystal structures and deformation methods of samples, some unusual properties in ultrafine grains pure copper are possibly unstable.
