Abstract

The microstructure of Fe-Cu-Ni-P model pressure vessel steels after neutron irradiation and thermal aging has been characterized by atom probe field-ion microscopy and augmented by transmission electron microscopy. High densities of small, roughly spherical or disc shaped copper clusters/precipitates were observed in the neutron irradiated alloys that contained copper. Small spherical phosphorus clusters were observed in the irradiated copper-free alloys, and copper phosphides were observed in a high phosphorus Fe-Cu-Ni-P alloy. None of these clusters/precipitates were observed in the thermally aged materials. The increases in the tensile and yield strengths that were observed after neutron irradiation resulted from these clusters and other lattice defects. 14 refs., 8 figs., 2 tabs.

Fine-scale microstructural characterization of pressure vessel steels and related materials using APFIM (atom probe field-ion microscope). [Atom probe field-ion microscopy]

Conference Miller, M; Burke, M

Atom probe field-ion microscopy has been used to characterize the ultra fine-scale microstructure of neutron-irradiated A302B and A212B pressure vessel steels, A533B submerged arc welds, and several model Fe/endash/Cu Alloys. The atomic spatial resolution of this technique permits a complete microstructural and chemical description of the ultra-fine features that control the mechanical properties to be made. A variety of ultra fine-scale features including roughly spherical and disc-shaped copper precipitates and clusters, copper atmospheres, copper phosphides, phosphorus clusters, spherical and rod-shaped molybdenum carbides, molybdenum phosphides, disc-shaped molybdenum nitrides, and iron nitride precipitates were observed in these materials. The presence of thesemore »« less
Microstructural investigations of as-fabricated, long-term thermally aged and neutron irradiated RPV materials: An atom probe study

Conference Pareige, P; Miller, M; Stoller, R

Atom probe field ton microscopy (APFIM) investigations of the microstructure of as-fabricated, long-term thermally aged ({approximately}100,000h. at 540{degrees}F (282{degrees}C)) and neutron-irradiated (6.6{times}10{sup 18} and 3.47{times}10{sup 19} n cm{sup {minus}2} (E>1 MeV) at {approximately}550{degrees}F (288{degrees}C)) surveillance materials from commercial reactor pressure vessel steels were performed This combination of materials and conditions permitted the investigation of potential thermal aging effects as well as the neutron-induced effects. The microstructural study focused on the quantification of the matrix chemistry and the detection and characterization of radiation-induced precipitates. The APFIM results indicate that there was no microstructural evolution after a long term-thermal exposure in weldmore »« less

Effects of helium/DPA ratio, alloy composition and cold work on microstructural evolution and hardening of {sup 59}Ni-doped Fe-Cr-Ni alloys neutron-irradiated at 465 C

Conference Kawanishi, Hiroshi; Hamilton, M; Garner, F

Three ternary austenitic alloys (Fe-15Cr-25Ni, Fe-15Cr-25Ni-0.04P, Fe-15Cr-45Ni in both annealed and cold worked conditions) were irradiated at 465 C to 0.15, 0.28, and 0.42 dpa at above core position in the Fast Flux Test Facility utilizing the Materials Open Test Assembly to study the separate and synergistic effects of He/dpa ratio, phosphorus addition, nickel content and cold work level on microstructural evolution and hardening. The helium/dpa ratio was varied by isotopic doping with {sup 59}Ni to enhance the production rate of helium. The helium production rate was evaluated to be 62 appm He/dpa in the {sup 59}Ni-doped specimens and 0.26more »« less
Development of a mechanistic understanding of radiation embrittlement in reactor pressure vessel steels: Final report

Technical Report Ebrahimi, F; Hoelzer, D; Venables, D; ...

The microstructures of a series of reactor pressure vessel (RPV) steels and model iron alloys with various Cu, Ni, and P contents were examined in unirradiated and neutron-irradiated conditions using high resolution analytical microscopy. Fractography techniques were also applied. Objectives were to isolate and identify the mechanisms by which these elements affect steel radiation embrittlement sensitivity as evidenced by notch ductility and tensile strength changes. Radiation hardening of a reference iron alloy was found associated with the formation of prismatic dislocation loops of an interstitial nature. A very low density of loops was observed for a low Cu-low P steelmore »« less
Microstructural characterization of irradiated PWR steels using the atom probe field-ion microscope

Conference Miller, M; Burke, M

Atom probe field-ion microscopy has been used to characterize the microstructure of a neutron-irradiated A533B pressure vessel steel weld. The atomic spatial resolution of this technique permits a complete structural and chemical description of the ultra-fine features that control the mechanical properties to be made. A variety of fine scale features including roughly spherical copper precipitates and clusters, spherical and rod-shaped molybdenum carbide and disc-shaped molybdenum nitride precipitates were observed to be inhomogeneously distributed in the ferrite. The copper content of the ferrite was substantially reduced from the nominal level. A thin film of molybdenum carbides and nitrides was observedmore »« less
