Advanced reactor vessel steels for reactors with

Jan 22, 2017 · A set of studies, tests, and technological works is performed to design promising high-strength vessel steels for reactors with supercritical coolant parameters. Compositions and technological parameters are proposed for the production of reference steel (within the limits of the grade composition of 15Kh2NMFA-A steel) and high-nickel steel. These steels are characterized by high properties Evaluation of Irradiation Embrittlement of A508 Gr 4N and Jun 17, 2002 · In this study, the microstructural changes caused by neutron irradiation have been characterized in A508 Grade (Gr) 4N-type steels ({approx}3.5% Ni) using a variety of state-of-the-art analytical techniques including 3D-Atom Probe Field-Ion Microscopy and Small Angle Neutron Scattering, along with post-irradiation annealing studies combining Positron Annihilation Lineshape Analysis and Irradiation effects on phase transformations Marquis Ion irradiation of Fe-Cr alloys. microstructure located at about 0.5 to 0.6 µm for implantations conducted using 5 MeV Fe ++ ions and ignoring all other aspects of the implanted regions, this work quantified the microstructure of Alloy 800H along the entire ion damage profile. The gradients of microstructure along the implantation depth

The obtained microstructures were mechanically The relevant microstructural and fractographic aspects exhibited by the materials are em-ployed in the interpretation of their mechanical behaviors A508 steel in Precipitation and hardening in irradiated low alloy steels A508 Gr. 4N and Gr. 3, respectively. The lower Mn in Gr. 4N reduces the irradiation hardening and embrittlement sensitivity, so as to offset the effect of high Ni. To compensate for low Mn, it is important to keep the S and other impurities low. Thus for RPV applications, A508 Gr. 4N is part of an alloy class known as su-perclean steels.
