Zusammenfassung:	The paper presents the study of the martensitic transformation in AISI-316 austenitic steel during high-pressure torsion in a new design tool at ambient and cryogenic temperatures. It was found that intensive cooling with nitrogen leads to significant structure refinement and martensitic structure with a high number of high-angle boundaries. 8 HPT cycles at cryogenic temperature allows to obtain the content of martensite up to 93%.
