Alloying and grain boundary structure effects on the radiation induced segregation response in Type 304 variants under neutron irradiation

Analysis of Phase Transformation Studies in Solute Addition Alloys

Deformation behavior of laser welds in high temperature oxidation resistant Fe-Cr-Al alloys for fuel cladding applications

Ferritic-structured Fe-Cr-Al alloys are being developed and show promise as oxidation resistant accident tolerant light water reactor fuel cladding. This study focuses on investigating the weldability and post-weld mechanical behavior of three model …

Degradation of concrete for nuclear structures: Identified mechanisms and knowledge gaps

Development of advanced oxidation resistant steel for ATF clad application

Microstructural characterization of deformation localization at small strains in a neutron-irradiated 304 stainless steel

A specific phenomenon - highly localized regions of deformation - was found and investigated at the free surface and near-surface layer of a neutron irradiated AISI 304 stainless steel bend specimen deformed to a maximum surface strain of 0.8\%. It …

Radiation Damage In Reactor Cavity Concrete

Relationship between lath boundary structure and radiation induced segregation in a neutron irradiated 9 wt.\% Cr model ferritic/martensitic steel

Ferritic/Martensitic (F/M) steels with high Cr content posses the high temperature strength and low swelling rates required for advanced nuclear reactor designs. Radiation induced segregation (RIS) occurs in F/M steels due to solute atoms …

Strain-induced phase transformation at the surface of an AISI-304 stainless steel irradiated to 4.4 dpa and deformed to 0.8\% strain

Surface relief due to localized deformation in a 4.4-dpa neutron-irradiated AISI 304 stainless steel was investigated using scanning electron microscopy coupled with electron backscattering diffraction and scanning transmission electron microscopy. …
