抄録

The evolution of microstructure and texture of 1050 aluminum sheets was investigated by the method of equal channel angular pressing (ECAP). Repetitive pressings were used on the same samples, up to a total of 8 pressings through the die, with the samples pressed following two different processing routes either without rotation (route A) or with rotation through 180° (route B). The result shows that the high angle grain boundaries increase, and the grain sizes are reduced with repetitive pressings. The rate of formation of the high angle grain boundaries depends upon the processing routes and is more rapid using route A than using route B. Moreover, the shear texture, composed of {001}<110> and {111}<110> components, was observed after 1 pressing. However, the texture, {001}<010> component specially, is reduced with the repetitive pressings. Such a change of texture does not depend upon the processing routes nearly. By subsequent annealing, the intensity of the {111}<110> component is not almost changed, but that of {001}<110> component decreases largely and no new texture component appears.
