Titanium alloy tensile properties after neutron irradiation
Irradiated specimens from three duplex annealed titanium alloys were tested in uniaxial tension in air from room temperature to 550/sup 0/C. The EBR-II irradiation temperature was 550/sup 0/C; the maximum fluence was 5 x 10/sup 22/ n/cm/sup 2/ (E > 0.1 MeV), or 37 dpa, the highest neutron exposure received by any titanium alloy. Alloy 6242S increased in strength due to reactor exposure by approximately 20% at test temperatures from room to 400/sup 0/C. The strength of alloy 5621S was unaffected by reactor exposure, while Ti-6Al-4V displayed strength reductions at 550/sup 0/C. Largely ductility losses of 75 to 80% of unirradiated material total elongation were noted after reactor exposure in all three alloys; however, reasonable postirradiation ductility of 0.9 to 8.8% remained in all alloys.
