Simulation studies of radiation swelling of nickel and its alloys

In the paper some experimental results of swelling simulation of nickel and its alloys irradiated with Ni+(E=3MeV), Ar+ and Xe+(E=2MeV) ions are considered. Temperature dependences of swelling have been obtained for different intercepts of a damage curve. A positive effect of scandium alloying on nickel resistance to radiation swelling is shown. Some possible mechanisms of the scandium effect on void nucleation and growth are considered. The effect of implanted argon on void formation in nickel is shown using the thin film technique
