Main aim of this paper is to describe the plastic deformation executed by ECAP during low cycle fatigue of steel AISI 316. Among others, main attention was fixed on mechanical properties after this treatment. Experiments were planned and realised at temperature ranging from room temperature up to 280 °C. After deformation the structure was investigated to evaluate accumulation of deformation, deformation temperature as well as above-mentioned final properties. Accumulated true (logarithmic) deformation varied from the value 2 to 8. Structures were investigated via scanning electron microscope JEOL JEM 2100. Mechanical properties were evaluated by conventional tensile test and penetration test. Selected samples were subjected to low-cycle fatigue. Statistic evaluation of angular disorientation and grain/sub-grain size was also carried out with use of electron diffraction (EBSD) in combination with scanning electron microscope FEG SEM Philips. The ECAP was applied on austenitic steel AISI 316.
