Abstract

A geometric model is proposed which describes specific features of the displacement and distortion of the end regions of the samples upon equal-channel angular pressing (ECAP). It is shown that, upon some ECAP, the volume occupied by the end regions can be relatively large. In such cases, the arising structure will be characterized by a substantial inhomogeneity, especially in relatively short samples or when using a small number of ECAP passes.
