摘要：
Corrosion-fatigue crack propagation experiments were conducted on several low-alloy steels in elevated temperature aqueous environments and experimental parameters included temperature, sulfur content of the steel, applied potential and dissolved hydrogen land in one case, dissolved oxygen) concentration in the water. Specimen potentials were controlled potentiostatically and the observation (or non-observation) of accelerated fatigue crack growth rates was a complex function of the above parameters. The interaction of electrochemical potential and sulfides in the crack enclave are discussed in Part 2, as well as the postulated explanation for the complex behavior.
