N2 - The stacking-fault energies (SFE) were measured by weak-beam TEM method, and deformation mechanisms in room and high temperature were characterized in terms of the effect of nitrogen addition on SFE in Si-added austenitic stainless steel (Fe-19%Cr-13%Ni-0.05%C-3%Si-x%N). Nitrogen addition resulted in decrease of SFE and changing the dislocation configuration from tangled to planar in room temperature. In high temperature, nitrogen addition resulted in the increase of dislocation density in the subboundary by the decrease of SFE. These results indicated that addition of nitrogen contributed to room and high temperature strength because of the decrease of SFE.
