In this work the high-pressure torsion process of AISI-316 stainless steel in cryogenic conditions is studied by means of finite element simulation. The stress and strain distributions are analyzed and compared with the ones obtained for ambient temperature. It is shown that the cooling to cryogenic temperature do not affect the equivalent strain distribution significantly. At the same time, the stress values are significantly different-with cryogenic cooling, the level of compressive stresses increases by about 20 %. The simulation of microstructure evolution in Deform-3D program showed that the use of cryogenic cooling makes it possible to further grind the original structure.
