12,18Cr-oxide dispersion strengthened (ODS) steels were irradiated at room temperature by single beam (2.2 MeV He+ or 3.0 MeV H+ or 21.0 MeV Si4+), dual-ion-beam (2.2 MeV He+ and 3.0 MeV H+) and triple-ion-beam (21.0 MeV Si4+, 2.2 MeV He+ and 3.0 MeV H+). Five combination of H, He, He+H, Si, Si+He+H irradiation were used. The mechanical properties of 12,18Cr-ODS steels exhibited that triple-ion-beam irradiation could strengthen irradiation swelling and hardening effect. Carbon segregation and several new carbon peaks appeared in the Raman spectrum of irradiated 12Cr-ODS steel. A clear correlation was established between the carbon distribution and the damage distribution.
► We report the mechanical and Raman spectroscopic studies on 12,18Cr-ODS steels. ► We study the synergistic effects of irradiation damage on ODS steels. ► Carbon segregation appeared in the spectrum of irradiated 12Cr-ODS steel. ► A correlation is established between the carbon and the damage distribution.
