Abstract

The near-threshold corrosion fatigue crack propagation behavior of Mil S-24645 HSLA steel, its weld metal and heat affected zone have been studied in simulated marine environments. Tests were conducted in air and ASTM seawater, at both the free corrosion potential and -1.0V (SCE), using a frequency of 0.2 Hz and a stress ratio, R = 0.1. The results were compared with previous data for Mil S-24645 and ASTM A710 steel tested at frequencies of 10 and 2 Hz. The influence of frequency, microstructure and cathodic protection on crack closure contributions in the near-threshold regime will be discussed.
