Irradiation-assisted stress corrosion cracking of materials from commercial BWRs: Role of grain-boundary microchemistry

Conference Chung, H M ; Ruther, W E ; Sanecki, J E ; ...

Constant-extension-rate tensile tests and grain-boundary analysis by Auger electron spectroscopy which were conducted on high- and commercial-purity (HP and CP) Type 304 stainless steel (SS) specimens from irradiated boiling-water reactor (BWR) components to determine susceptibility to irradiation-assisted stress corrosion cracking (IASCC) and to identify the mechanisms of intergranular failure. The susceptibility of HP neutron absorber tubes to intergranular stress corrosion cracking (IGSCC) was higher than that of CP absorber tubes or CP control blade sheath. Contrary to previous beliefs, susceptibility to intergranular fracture could not be correlated with radiation-induced segregation of impurities such as Si, P, C, N, or S,more »« less

Modeling grain boundary microchemistry related to IASCC (irradiation-assisted stress corrosion cracking)

Conference Simonen, E P ; Jones, R H

Radiation effects on grain boundary and near grain boundary microchemistries are modeled and compared to measured radiation effects. Nonequilibrium diffusion mechanisms are shown to be consistent with measured phosphorus impurity segregation and measured chromium depletion resulting from irradiation. Radiation enhanced equilibrium segregation (impurity enrichment) and radiation enhanced chromium depletion (sensitization) kinetics are predicted to be sufficient to promote equilibrium effects but measurements do not confirm the radiation enhanced mechanisms. Likely causes for the discrepancy are solute trapping and precipitation effects in the matrix promoted by irradiation. Ion and neutron irradiation of austenitic steels are evaluated relative to causes for irradiation-assistedmore »« less

Roles of Vacancy/Interstitial Diffusion and Segregation in the Microchemistry at Grain Boundaries of Irradiated Fe-Cr-Ni alloys

Journal Article Yang, Ying ; Field, Kevin G. ; Allen, Todd R. ; ... - Journal of Nuclear Materials

A detailed analysis of the diffusion fluxes near and at grain boundaries of irradiated Fe–Cr–Ni alloys, induced by preferential atom-vacancy and atom-interstitial coupling, is presented. The diffusion flux equations were based on the Perks model formulated through the linear theory of the thermodynamics of irreversible processes. The preferential atom-vacancy coupling was described by the mobility model, whereas the preferential atom-interstitial coupling was described by the interstitial binding model. The composition dependence of the thermodynamic factor was modeled using the CALPHAD approach. The calculated fluxes up to 10 dpa suggested the dominant diffusion mechanism for chromium and iron is via vacancy,more »« less
