Abstract

To determine the crack growth under the actual loading conditions in structural components exposed to aggressive environments during service operation, the effects of the stress intensity rate (K), stress ratio (R), and maximum stress intensity factor of cyclic loading on the corrosion fatigue crack growth rate are examined using a Cr-Mo low alloy steel - 0. 1 N H//2SO//4 system. Results obtained show that the enhanced crack growth rate can be described by a given equation. The stress intensity rate exercised much influence on the corrosion fatigue crack growth rate.
