The investigation of strain state and microstructure evolution of AISI-316 austenitic stainless steel during high-pressure torsion process in the new stamp design was performed. The study using Deform-3D program was con-ducted. The deformation was carried out at ambient temperature. The results of strain state study showed that after 4 passes the processed workpiece is obtained the level of equivalent strain more than 5. But the distribution of strain has a gradient view in the cross section. The simulation results of the microstructure evolution showed that after 4 passes of deformation the initial grain size of 12 µm can be reduced up to 0,8 µm. But the distribution of grain size in the cross section also has a non-uniform gradient view.
