MIBL and Argonne Experiments Track Cavity Evolution in Alloy 800H
A new Acta Materialia study led by Xingyu Liu investigates cavity evolution in irradiated alloy 800H. Dual-ion irradiations at MIBL provided the foundation for subsequent in situ experiments at Argonne National Laboratory’s Intermediate Voltage Electron Microscope.
The team tracked individual cavities as they interacted with displacement cascades at different dose rates. The observed temperature-dependent behavior provides insight into how irradiation conditions affect cavity stability and how ion experiments can be used to study neutron-induced swelling. The research grew from an NSUF Rapid Turnaround Experiment award.
