A systematic study of the influence of plastic deformation and low temperature ageing on the carbon Dislocation - Enhanced Finkelshtain - Rosin Effect (DEFRE/C) in austenitic alloys of Fe-Ni, Fe-Ni-Mo, Fe-Mn-Al and Fe-Cr-Ni systems with different carbon content is reported. The experiments prove that after plastic deformation at room temperature the FR effect is transformed into DEFRE/C, with both phenomena occurring at the same temperature. The influence of plastic deformation, carbon and alloying elements concentration on DEFRE/C in deformed austenitic steels is reported.
