70 MeV-carbon-ion irradiation is used to simulate the radiation swelling induced by neutron irradiation of 3.2 × 10~(22) n·cm~(-2) in domestically-made 316 austenitic stainless steels modified by a 20%-cold-working and Ti-adding from room temper- ature to 802℃. The created swelling is microscopically examined by the positron annihilation lifetime technique. A radiation swelling peak is observed at 580℃ and the corresponding void has an average diameter of 0.7 um which is hardly probed by macroscopic methods.
