The effects of neutron irradiation at 590 to 750 deg C on the tensile properties of three steels were studied. 20 Cr/25 Ni/Nb (0.01 wt% C, 0.7 wt% Nb), 20 Cr/25 Ni/Ti (0.01 wt% C, 0.3 wt% Ti), and 20 Cr/25 Ni/LC (low carbon, 0.005 wt% C, unstabilized). The specimens were in the form of 0.5 mm thick strip tensile specimens with a 25 mm x 6 mm gauge length and were tested over the temperature range 500 to 900 deg C. After irradiation at 590 and 750 deg C, only the 20 Cr/25 Ni/LC steel showed a small but consistent fall in UTS values. The major effect was a reduction in ductility of all three steels, which was accompanied by a change in fracture characteristics. (P.C.H.)
