Fatigue tests measured with acoustic emission (AE) method have been conducted on a low-strength structural steel in either air or 3.5 pct NaCl solution. The results show the relation between AE count rate and crack growth rate or stress intensity factor range. The AE activity during the fatigue process decreases in solution in comparison with that in air. Furthermore, a model of AE behavior is proposed, and the difference of AE activity between fatigue and corrosion fatigue (CF) depends upon the effects of both the decrease of plastic zone size and material embrittlement at the crack tip.
