    The dislocation substructure of AISI 304 and 316 stainless steels resulting from high strain fatigue for various strain rates at temperatures ranging from 430 to 816 C has been evaluated by transmission electron microscopy. The substructure is characterized quantitatively and correlated with the observed mechanical behavior. Dislocation cells or subgrains were observed for all test conditions with exception of one test where failure occurred in the high-cycle range. These results suggest that a change in deformation mechanisms appear to occur between 650 and 816 C. The Hollomon strain hardening equation is written in terms of the dislocation cell size for both monotonic and cyclic loading predicting higher strengths and strain hardening capabilities could be effected through cell size refinement.
