A special design of the die was developed, which allows to implement the process of severe plastic deformation by high pressure torsion to deform ring blanks, which will be the starting material for creating high-strength piston rings. A special feature of the die design is the provision of torsion of the deforming tool with constant rectilinear movement of the press punch due to the composite deforming tool, which includes both displacement and rotation blocks. Using the obtained geometry, computer simulation of this process in the Deform program was performed in order to assess the possibility of a stable process flow. AISI-316 austenitic stainless steel was chosen as the material of the billet. The resulting strain force on the first two cycles was considered. On the first cycle, the force was equal to 464 kN, on the second cycle the force value was about 1200 kN. The obtained values are quite adequate, which indicates the possibility of multi-cycle deformation.
