Shear Punch Testing of BOR60 Irradiated HT-9 and 14YWT
- Los Alamos National Laboratory (LANL), Los Alamos, NM (United States)
Ferritic/martensitic (FM) steels and nanostructured ferritic alloys (NFA) are being developed for next generation reactor applications. Applications such as transmutation of long lived isotopes in used fuels require cladding materials that can withstand high irradiation doses, potentially in the hundreds of displacements per atom (dpa). The FM steels in this report include HT-9 steel, which is a Fe-12Cr steel with additions of Mo, Mn, Ni, V and W. An oxide dispersion strengthened (ODS) 14YWT is also presented, which has a distribution of nano-scale oxide particles throughout the microstructure. Shear punch testing was performed on both steels. The material was neutron irradiated at the BOR60 reactor in Russia and transferred to LANL for shear punch mechanical testing. These results are complementary to a previous report, also from a BOR60 irradiation.
