摘要: Abstract The ion irradiation hardening behaviors of Fe–9 wt% Cr and Fe–20 wt% model alloys were investigated by nanoindentation technique. specimens irradiated with 3 MeV Fe 11+ ions at room temperature up to 1 5 dpa for Fe–9Cr alloy 2.5 Fe–20Cr alloy. ratio average hardness in the same depth unirradiated (Hirr. av/Hunirr. av) was used determine critical indentation hcrit eliminate softer substrate effect. Nix–Gao explain size Irradiation is clearly observed both after irradiation. differences ISE between are considered be due their different microstructures microstructural evolution under
