Annotation

The  paper considers the problem of calculation of the plasticity margin in the region of noncontact zones when rolling AK6 alloy and determining the compression ratios at which its destruction becomes possible.

For the theoretical study of the indicators characterizing plasticity, a finite element program for 3D modeling of the bulk forging technology QForm and the engineering mathematical program MathCad was used.

The constructed graphs of the plasticity diagrams, the deformation paths at different drawing ratios, showed the most "defect-dangerous" deformation interval. The carried out studies of the change in the used plasticity resource and the curvature of the deformation trajectory along the deformation course made it possible to calculate the maximum permissible degree of shear deformation for the investigated process for Kolmogorov and Ogorodnikov criteria and to estimate the most suitable one for describing the deformability of the metal in the region of noncontact zones during rolling.

Keywords: plasticity, rolling, criterion of destruction, way of deformation, used plasticity resource.
