Peculiarities of Rheologically Complex Metals Flow while Rolling it with Superreductions

It was established that while rolling a rheologically complex metal under conditions of the moderate (e ≈ 0, 2 - 0, 3) single degrees of deformation in consequence of exceptionally high unevenness of deformation in the section of zone of deformation being near the contact with rolls are forming nuclei of the maximum intensity of the rate of deformation, Hmax. During the time of passage through these nuclei metal is softening and the surface layers of metal are flowing with the rate greater than the depth ones to the excit from zone of deformation. In the case of rolling rheologically complex metal under conditions of the extra great single deformations (e ≥ 1) the nuclei Hmax close up forming the common zone of metal softening. In the end this decreases energy expense for deformation.
