Abstract

The stability of nano-scale oxides with the size less than 5 nm in the helium atmosphere under irradiation in the ODS (oxide dispersion strengthened) materials was researched. The 14YWT alloy with pre-implanted with helium was irradiated at high temperature. Size, density, and composition of the nano-scale oxides were investigated by the atom probe tomography. The results show that nano-scale oxides are composed of oxides enrich in Ti and Y. The change of the size and composition of the nano-scale oxides under irradiation is trivial, indicating the good stability of nano-scale oxides in helium pre-implanted ODS materials under irradiation at 600℃.
