dc.description.abstractUsing a computer simulation it was conducted a study of new modification of the combined process ``rolling-pressing``, the distinctive feature of which is the use at the exit of equal-channel step matrix vertical rolls instead of horizontal rolls. It was performed the investigation on the stress-strain state, the deformation of the workpiece and the microstructure evolution. The values obtained were compared with those of the model with two pairs of horizontal rolls. As a result, it was found that the use of vertical rolls at the exit of the equal-channel step matrix has the following advantages: the treatment of the workpiece is more uniformly throughout the section; in general, by changing the direction of compression during rolling in the vertical rolls the deformation occurs at much lower values of the extrusion, which entails a slight change in the original dimensions of the workpiece; the initial grain size is reduced more intensively both on the surface and in the central zone.
