Grain boundary segregation and intergranular stress corrosion cracking susceptibility of austenitic stainless steels in high temperature water

Conference Shoji, T ; Yamaki, K ; Ballinger, R G ; ...

The effects of grain boundary segregation on intergranular stress corrosion cracking of austenitic stainless steels in high temperature water have been examined as a function of heat treatment. The materials investigated were: (1) two commercial purity Type 304; (2) low sulfur Type 304; (3) nuclear grade Type 304; (4) ultra high purity Type 304L; and (5) Type 316L and Type 347L. Specimens were solution treated at 1050{degrees}C for 0.5 hour and given a sensitization heat treatment at 650{degrees}C for 50 hours. Some of the specimens were then subjected to an aging heat treatment at 850{degrees}C for from one to tenmore »« less
Grain boundary segregation in austenitic stainless steels and effects on intergranular stress corrosion cracking in light-water reactor environments

Conference Bruemmer, S M

Grain boundary composition in austenitic stainless steels established by various equilibrium and nonequilibrium processes is assessed and its possible influence on intergranular stress corrosion cracking (IGSCC) in light-water reactor environments examined. Interfacial Cr concentration is shown to be the dominant material variable promoting IGSCC of austenitic stainless steels in oxidizing high-temperature water. Cracking susceptibility is a direct function of the boundary Cr content regardless of depletion width. Small levels of depletion, 1 to 2 wt% below bulk Cr concentrations (below {approximately}17 wt% for 304SS), are sufficient to promote IGSCC. As a result, many observations of irradiation-assisted (IA) SCC in boiling-watermore »« less
Linking Grain Boundary Structure and Composition to Intergranular Stress Corrosion Cracking of Austenitic Stainless Steels

Conference Bruemmer, Stephen M

Grain boundary structure and composition is assessed in austenitic stainless steels along with its influence on intergranular stress corrosion cracking (IGSCC) in high-temperature water. Brief examples are presented illustrating effects of grain boundary character and segregation on behavior in specific light-water-reactor environments. Although grain boundary engineering can produce an increased fraction of special boundaries in austenitic stainless alloys, practical benefits depend on the boundary orientation distribution. It is critical to recognize that only coherent sigma 3s appear to be resistant to SCC and the behavior of other low sigma boundaries is uncertain. Grain boundary composition can have a dominant effectmore »« less
Grain Boundary Character Along Intergranular Stress Corrosion Crack Paths in Austenitic Stainless Alloys Removed from High-Temperature Water Service

Conference Gertsman, Valerii Y ; Bruemmer, Stephen M

Stress-corrosion cracks produced in high-temperature water environments were examined in alloy 600 and stainless steel samples. The alloy 600 samples were removed from pressurized-water reactor (PWR) steam generator tubing after exhibiting cracking in service or after model-boiler stress corrosion cracking tests. The 304 and 316 stainless steel samples also experienced intergranular stress corrosion cracking (IGSCC) in high-temperature-water environments similar to a PWR steam generator. Grain boundary misorientations were measured along IG crack paths as well as in the bulk. In general, only twin Sigma 3 boundaries exhibited improved resistance to crack propagation. If the Sigma 3 were factored out, themore »« less
STUDY OF GRAIN BOUNDARY CHARACTER ALONG INTERGRANULAR STRESS CORROSION CRACK PATHS IN AUSTENITIC ALLOYS

Journal Article Guertsman, Valery Y ; Bruemmer, Stephen M - Acta materialia, 49(9):1589 - 1598

Samples of austenitic stainless alloys were examined by means of scanning and transmission electron microscopy. Misorientations were measured by electron backscattered diffraction. Grain boundary distributions were analyzed with special emphasis on the grain boundary character along intergranular stress-corrosion cracks and at crack arrest points. It was established that only coherent twin S3 boundaries could be considered as "special" ones with regard to crack resistance. However, it is possible that twin interactions with random grain boundaries may inhibit crack propagation. The results suggest that other factors besides geometrical ones play an important role in the intergranular stress-corrosion cracking of commercial alloys.
