Atomistic modeling of helium bubble network formation in copper
Source abstract
Abstract
The helium (He) bubble network formation process in bulk copper (Cu) is investigated using atomistic simulations. Self-interstitial atoms (SIAs) emitted by trap mutation during the growth process of a single He bubble change surrounding lattices and stress fields and affect the transport of nearby He atoms . Interstitial He atoms or dimers can become trapped by deformed lattices and become nucleation sites for new He bubbles. The interaction of He with SIAs mutually hinders their movements. Finally, a distributed network of He bubbles, which are mostly formed along stacking fault edges, is generated. System temperature and He insertion rate have significant influences on this network.
