Multiscale investigations of severe plastic deformation

The present paper represents the results of an application of the multiscale approach to study severe plastic deformation (SPD). These investigations were used to reveal the features of material flow and crystallographic texture development in bulk Cu ingots subjected to SPD by equal-channel angular (ECA) pressing. The influence of the processing parameters such as the outer and inner curvature radii of the channels and the friction coefficient on the homogeneity of the above mentioned characteristics at the first ECA pressing pass has been studied.
