“…The inner layer is more homogeneous, but it also varies in its thickness, particularly with regard to its penetration into the substrate steel. While such variation in thickness is probably due in part to the level of polishing of the surface (to 600 grit) performed prior to the pre-oxidation, it has also been observed by other researchers [11,15].

“…Caré et al [42] found that the elastic modulus of rust was not constant but rather would increase with time. Hosemann et al [43] developed nano-indentation tests on the rust samples and showed that the range of elastic modulus values was 70-100 GPa. Bhargava et al [2,10] took the effective elastic modulus of the steel-rust product composites as 210 GPa which is the same as that of reinforcement.…”

A double-cylinder model incorporating confinement effects for the analysis of corrosion-caused cover cracking in reinforced concrete structures, Corros. Sci. (2015), http://dx. a b s t r a c tIn this paper, a double-cylinder model with a consideration of concrete confinement effects is proposed to simulate reinforcement corrosion-caused cover cracking. The analytical model incorporates force equilibrium in both tangential and radial directions as well as volume expansion and deformation compatibility in the steel-rust-concrete interface. Confinement effects outside the cylinders are taken into account by comparing the numerical and available experimental results. Parametric studies are conducted to investigate the variations of the critical volume of consumed steel, critical expansive pressure and time to cover cracking.

“…Micro pillars could be cut from the original sample and placed on an "anvil" and transported to a nanoindenter and tested. In this and previous work [6,13] it has been shown that a sample of 8×8×16 μm is sufficient to perform micro mechanical tests on irradiated F/M materials. Using this volume as a comparison point, one micro pillar cut from a STIP tensile sample has 2.55 Bq which is again just below background levels.…”

“…HT-9 is considered for in core structural components in the USA because of its substantial dataset on radiation induced property changes [2][3][4][5]. In addition, the performance of HT-9 in contact with lead bismuth eutectic coolants has been examined in relevant fast reactors environments [6,7]. After the actual STIP irradiation the samples were stored for a period of 62 month in order to allow for a decay of the shorter lived isotopes.…”

The Fuel Cycle R&D (FCRD) initiative is investigating methods of burning minor actinides in a transmutation fuel. To achieve this goal, the fast reactor core materials must withstand very high doses. Small scale materials testing methods in addition to large scale materials testing allows one to gain more insight by providing more data on the same sample while being able to probe areas of interest which are not accessible otherwise. Furthermore, the sample volumes were so small that the tests could be considered a non destructive test since the amount of material needed is so small that a macroscopic structure would not be affected. Tensile testing, micro hardness testing and micro compression testing on focused ion beam (FIB) microscope manufactured pillars were performed on remaining parts of tensile test specimens tested and irradiated in the Spallation Target Irradiation Program (STIP). It is shown that the increases of yield strength measured by tensile testing, micro compression testing and micro hardness testing all showed the same trend. In addition FIB based techniques also allowed fabrication of LEAP samples of such a small size that their residual activity was below detectable levels thus allowing them to be handled and analyzed in a manner comparable to inactive specimens.Keywords Micro compression testing .
