| Abstract: | The fatigue crack propagation behaviour of two mild steels with vari-
ous microstructures in 3.5% NaCl solution or atmosphere was studied. It is revealed
that the microstructures of steel and frequency have considerable influence on the
corrosion fatigue strength. The relation between crack closure effect and electroche-
mical conditions is discussed. The corrosion fatigue mechanisms, which consider
the effect of hydrogen embrittlement and anode dissolution respectively, are pro-
posed. A fracture mechanism-map is worked. |

| Keywords: | corrosion fatigue fracture mechanism mild steel |
