抄録

Pulse and steady-state heating effects on the microstructure of nickel implanted with helium or deuterium ions have been investigated, in order to examine the combined effects of particle bombardment and heat loading on the plasma-facing components of fusion reactors. Large dimensional changes of the plasma-facing surfaces due to bubble growth is expected when they are implanted with helium or hydrogen isotopes and then pulse heated. Grain boundary degradation may be small, however, for the case of pulsed heating because of the small accumulation of bubbles at the grain boundaries.
