Abstract
The results of experimental investigations of the CEC processes, performed on a new special hydraulic press with control back-pressure, are presented for the first time. Due this very advantageous conditions of plastic deformation very interesting and unique experimental results, enabling accurate determination of the directions of shear bands formation were obtained. It has been observed that after very large plastic deformation of the solution heat-treated 6082 alloy, taking squares in the presence of high hydrostatic pressure, he the surface of the deformed samples an easily noticed relief is formed, resulting from the formation of numerous intersecting shear bands. It has been found that under conditions of hydrodynamic lubrication, all shear bands are formed at the angle of 45̇ this the extrusion direction and their intersection occurs at the angle of 90̇. Such mechanism of shear bands formation allowed determining the true state of strain and stress, occurring in the deformation zone of the CEC processes.
