Abstract The stress corrosion cracking (SCC) behavior of the U-4.5 wt% Nb alloy aged 80 hours at 260 C (500 F) has been investigated. Smooth four point bend SCC tests and smooth static tensile SCC tests were used. The results of this study show that aged U-4.5 wt% Nb alloy is susceptible to SCC when stressed and exposed to water containing oxygen and chloride ions. The stress corrosion cracks which nucleate in the aqueous chloride environments proceed by an intergranular SCC fracture mode. No failures were observed in dry air containing less than 200 ppm moisture or in 100% relative humidity air. The surface tensile stress required for SCC is less than 20,000 psi in oxygen saturated water containing 50 ppm chloride ions.
