摘要：

Different face-centred cubic (fcc) metals (Ni, Cu, Ag) have been deformed one pass by equal channel angular pressing. The texture with respect to position in the deformed billet has been measured with high-energy synchrotron radiation. It is characterized by texture components typical for simple shear in the intersection plane of the square-shaped 90 degrees bent channel. Intensities of the texture components as well as deviations from their ideal shear positions vary from the top to the bottom of the billet. The change of the intensity of texture components and the texture gradient within the metals investigated is discussed. Special emphasis is put on the influence of stacking fault energy on texture formation during ECAP of fee metals.
