High-dose neutron induced radiation swelling simulated by heavy ion irradiation and its microscopic study with positron annihilation technique

70MeV-carbon-ion irradiation is used to simulate the radiation swelling induced by neutron irradiation of 3.2 ×10^22n.cm^-2 in domestically-made 316austenitic stainless steels modified by a 20%-cold-working and Ti-adding from room temperature to 802℃,The created swelling is microscopically examined...

Description
Summary:70MeV-carbon-ion irradiation is used to simulate the radiation swelling induced by neutron irradiation of 3.2 ×10^22n.cm^-2 in domestically-made 316austenitic stainless steels modified by a 20%-cold-working and Ti-adding from room temperature 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 nm which is hardly probed by macroscopic methods.
