Shielded magnetic small-angle neutron scattering for characterization of radioactive samples. [PDF]

J Appl Crystallogr
The study presents a novel shielded magnetic small‐angle neutron scattering (SM‐SANS) technique using lead shielding to facilitate the nanoscale characterization of clustering and precipitation in highly radioactive nuclear materials. By comparing the results with atom probe tomography, the research demonstrates that SM‐SANS effectively quantifies ...

Outstanding 1200 °C Oxidation Resistance in a Novel Multi-Principal Element Alloy via Lattice Distortion-Induced Diffusion Suppression. [PDF]

Adv Sci (Weinh)
The unique lamellar structure of the eutectic alloy promotes selective oxidation of Al initially, while lattice distortion‐induced diffusion suppression slows oxide growth during steady state. Combining these strategies, a Multi‐Principal Element Alloy with excellent oxidation resistance at 1200℃ was designed.

Radiation Damage Mitigation in FeCrAl Alloy at Sub-Recrystallization Temperatures. [PDF]

Materials (Basel)
Traditional defect recovery methods rely on high-temperature annealing, often exceeding 750 °C for FeCrAl. In this study, we introduce electron wind force (EWF)-assisted annealing as an alternative approach to mitigate irradiation-induced defects at significantly lower temperatures.
