The authors wish to thank S. P. Grant for his continued interest and encouragement of atom probe studies of RPV materials. This research was sponsored by the Division of Materials Sciences, U.S. Department of Energy, under contract DE-AC05-96OR22464 with Lockheed Martin Energy Research Corp., by the Office of Nuclear Regulatory Research, U.S. Nuclear Regulatory Commission under inter-agency agreement DOE 1886-N695-3W with the U.S. Department of Energy, and through the SHaRE Program under contract DE-AC05-76OR00033 with Oak Ridge Associated Universities. This research was conducted utilizing the Shared Research Equipment User Program facilities at ORNL. Studies of the French pressure vessel steels and some model alloys were performed at the “Equipe de Sonde Atomique et Microstructures” of the GMP-UMR CNRS 6634 of the Rouen University and were financially supported by Electricité de France Département Etude des Matériaux” under EDF/CNRS contracts.

N2 - A review of the contributions of the atom probe field-ion microscopy (APFIM) techniques to the microstructural characterization of pressure vessel steels and to the understanding of the embrittlement of these materials during neutron irradiation is presented. Atom probe studies have revealed that the microstructure contains a variety of ultrafine clusters and precipitates some of which are only formed during neutron irradiation. Furthermore, there is a complex pattern of segregation of various solutes (including phosphorus, nickel, manganese, or molybdenum) to grain boundaries in some pressure vessel materials, and there may also be additional intergranular precipitation in these materials.
