Abstract
In the development of new technology metal forming the main purpose is improvement the quality of the source material. The main aspect of quality improvement is increasing the strength characteristics. Often to increase the strength of deformable metal should be given reduced grain structure, up to subultra and even nanolevel. There are several ways to obtain sub-ultra-fine-grain structure of metals, and one of those ways is a method of severe plastic deformation (SPD), implemented in the whole volume of the deformable metal.In this work computer modeling was performed of the combined process "rolling-pressing" with the use of grooved rolls and equal channel step matrix with varying basic geometric and technological factors which have a significant impact on the process, what was made for the analysis of the impact of various factors on the stress-strain state of the process.
