摘要

Abstract

The irradiation stability of amorphous SiOC and crystalline Fe interface was investigated by in-situ Kr ion mixing. Results showed intermixing between Fe and SiOC was most severe for irradiation at 50 K and the intermixing decreases as irradiation temperature increases. These findings suggest two characteristic regimes of ion mixing: one regime is independent of temperature and due to ballistic mixing and the other regime is dependent on temperature and is referred to as radiation-enhanced demixing. The occurrence of the temperature-independent mixing and temperature-dependent demixing regimes indicates that the Fe/SiOC nanocomposite is thermodynamically stable and radiation tolerant at elevated temperatures.

IMPACT STATEMENT

This report reveals two characteristic ion mixing regimes in Fe/SiOC system: one temperature-independent regime and the other temperature-dependent demixing regime

indicating its thermodynamically stability and radiation tolerance at elevated temperatures.
