چکیده انگلیسی
Transmission electron microscopy studies and nano-indenter tests were used to examine model alloys of V-4Cr-xTi (where x is less than 1â¯wt.%) that were irradiated in a nuclear reactor with neutrons and irradiated in an ion accelerator with He ions. Void formation resulted in V-4Cr-0.1Ti and 0.3Ti from 400â¯Â°C to 600â¯Â°C with a damage level of 21 dpa in neutron irradiation. No void formation was visible in V-4Cr-1Ti. A threshold concentration of void formation and Ti(CON) precipitate formation occurred for xâ¯=â¯0.3â¯wt.% to 1â¯wt.% in the V-4Cr-xTi alloy. Void formation and Ti(CON) precipitation competed in neutron irradiation as caused by vacancy migration depending on the concentration of the added Ti in the V-4Cr-xTi alloy. A study of the He-ion irradiation indicated the same competitive process of void formation and Ti(CON) precipitate formation depending on the added Ti concentration.
