NSUF 24-5164: Investigating effect of dose rate on microstructure evolution in 800H alloy at high doses

The proposed Rapid Turnaround Experiment (RTE) aims at elucidating the effect of dose rate on precipitate dissolution and the effect of local chemistry on the cavity formation at high doses. The microstructure evolution observed during in-situ dual ion irradiation will bridge the knowledge gap between neutron irradiation damage and dual ion irradiation damage at high doses. By leveraging the newly established in-situ dual ion irradiation capability in Intermediate Voltage Electron Microscope (IVEM) facility at Argonne National Laboratory, we aim to unravel the interactions between radiation-induced precipitates and cavities and establish fundamental understandings of dose-rate effects on defect evolution in 800H alloys, thus enabling more accurate emulation of neutron damage using accelerated ion irradiation.
