Abstract The alteration of substructure of an austenitic stainless steel hasbeen investigated during constant strain fatigue. No plateau stage on the cyclicstress-strain curve was observed for the stainless steel in contrast with a mono-crystalline pure copper specimen. This may be related to its low stacking fault en-ergy. During strain fatigue under various amplitudes the substructure of dislocationin austenite alterates correspondingly. It revealed to be associated with the appear-ance change of the cyclic stress-strain curve.
