Abstract

The effects of crack closure on the near-threshold corrosion fatigue crack growth behavior of Mil S-24645 HSLA steel and its weld metal have been investigated in air, ASTM seawater at the free corrosion potential and ASTM seawater at -0.8V and -1.0V (SCE) using frequencies of 10, 2 and 0.2 Hz, and a stress ratio, R= 0.1. Remaining life, in the presence and absence of crack closure, has been estimated as a function of applied stress range for a structure containing a 3 mm deep surface semi-elliptical flaw.
