Stress-Corrosion Cracking of Hgh-Strength Steels and Titanium Alloys

Abstract

One of the major problems of metal structures in the seawater environment is the growth of flaws by the stress-corrosion-cracking (SCC) mechanism. Environmental effects on the integrity of the structure are related both to SCC processes and to the inherent tolerance of the material for flaws at regions of high stresses. The Ratio Analysis Diagram (RAD) provides translations of fracture resistance properties of metals to expected structural performance; the RAD has been modified to include analyses of the effects of SCC. The significance of section-size effects on the results of SCC tests based on linear-elastic analysis methods and expected structural behavior are included on the modified diagram, which is called the Dual-SCC RAD. Examples of several current high-strength steels and titanium alloys are referenced to the Dual-SCC RAD to illustrate its use.
