The mechanical properties behavior of one low carbon steel, SAE 1018, and two nuclear pressure vessel steels, A533B Class I and A533B Class II, all with similar compositions, are examined after fatigue in the elastic regime. Specimens which had undergone the fatigue treatment were then tensile and notch tensile tested to determine mechanical properties changes. Electron microscopy techniques were used to characterize the microstructure developed during fatigue. The results show that mechanical properties are effected by elastic fatigue. In general, the materials are more ductile after fatigue than in the as-recieved condition. The microstructural examination indicates that this change is due to the dislocation substructure which is developed during fatigue.
