STRESS-CORROSION CRACKING OF HIGH-STRENGTH ALLOYS

Abstract

A stress-corrosion-cracking investigation was performed on 1 heat of 20%-nickel maraging steel, 5 heats of 18%-nickel maraging steel, and 6Al 4V titanium alloy. These alloys were tested under three metallurgical conditions: (1) annealed and maraged, (2) cold-reduced and maraged, and (3) welded and maraged. Test environments included aerated distilled water, tap water, and 3% NaCl and 0.25% sodium dichromate solutions, as well as ambient air, 140 F water saturated air, seacoast atmospheric exposure, hydrocarbon oil, soluble oil-water mixtures and trichoroethylene. Test methods included both two-point loaded beams and tensile-loaded samples having fatigue-crack stress-raisers.
