| Abstract Scope |
As a part of the STRUMAT-LTO project, we are investigating the synergetic effects of Mn, Ni, and Si on the formation of Mn-Ni-Si clusters at higher neutron fluences. Six reactor pressure vessel model steels, with different content of Mn, Ni, and Si, were produced for this work. The samples were irradiated to a neutron fluence of ~1.11 × 1020 n cm–2 (E > 1 MeV) at 283 °C; with a flux of ~2.75 × 1012 n cm–2 s–1. Atom probe tomography (APT) was used to gather the microstructural information for all the alloys in unirradiated and irradiated conditions. The unirradiated samples do not show any clustering tendency. The hardening of samples after neutron irradiation trends with the increase in Ni content. Mn and Ni show a synergetic effect on hardening. The APT results on the unirradiated and the irradiated samples will be presented and discussed. |
