Research Abstract

Stress corrosion cracking (SCC)of austenitic alloys in simulated boiling water reactor (BWR)environments and pressurized water reactor (PWR)environments are measured. The effects of mechanical anisotropy and environmental parameters were investigated by experimental and theoretical methods. In a simulated PWR primary water, a significantly higher growth rate was observed in a 1-D rolled 316L stainless steel (SS)than those in a 3-D rolled 316L SS. SCC growth rates of 304NG SS after 1-D rolling are higher in the T-L orientation than those in the L-T orientation in both oxygenated and hydrogenated water at 288 oC. The mild inhibiting effect of decreasing electrode potential on crack growth of cold-rolled SSs is analyzed. Microstructure and local misorientation in 316NG SS weld heat-affected zones were measured and correlated to SCC in high temperature water.
