Two titanium alloys were irradiated at 50 and 350°C to ~0.3 dpa. Tensile properties were determined for both alloys and related to the observed microstructure before and after deformation. Radiation hardening occurred in both alloys when irradiated at 50°C due to the presence of fine-scale defects, whereas at 350°C only the Ti-6Al-4V alloy showed significant hardening. Radiation-induced precipitation occurred in this alloy, yielding a high strength, lower ductile condition compared to the unirradiated condition.
