摘要：
Using equal-channel angular pressing as an example, the effect of metal-flow kinematics under condition of severe plastic deformation of metals on the value of strain and features of structural changes is considered. The role of shear and rotational strain in the formation of ultrafine-grained structures is shown and the contribution into the total deformation is defined.
