Empirical validation of size effects in sub-sized tensile specimens for nuclear structural materials
Advancing the understanding of material behavior and phenomena related to the size effect in small-scale components is important for settings where limited quantities of material samples can be tested. Through research and collaborative efforts, the scientific community and industry stakeholders have established guidelines for sub-sized specimen testing, encompassing best practices for specimen preparation, testing equipment, […]
Hydrogen permeation in iron-chromium-aluminum (FeCrAl) alloys and the effects of microstructure and surface oxide
Iron–chromium–aluminum (FeCrAl) class alloys are candidates for use as cladding for accident-tolerant fuels and moderators. In this context, hydrogen isotope permeation in FeCrAl alloys is an important material property. In the present work, the apparent permeability, effective diffusivity, and apparent solubility of hydrogen in the FeCrAl alloys C26M and Kanthal D (KD) were measured with […]
Dataset of tensile properties for sub-sized specimens of nuclear structural materials
Mechanical testing with sub-sized specimens plays an important role in the nuclear industry, facilitating tests in confined experimental spaces with lower irradiation levels and accelerating the qualification of new materials. The reduced size of specimens results in different material behavior at the microscale, mesoscale, and macroscale, in comparison to standard-sized specimens, which is referred to […]
