Abstract

This work reports on Helium (He) accumulation in novel metal nanocomposites fabricated by phase separation in three-dimensions. These nanocomposites are dense with semi-coherent interfaces that ultimately influence He implantation response. The effect of film morphology on three aspects of He response is investigated: size and distribution of He precipitates, He retention, and He-induced changes in mechanical properties. Transmission electron microscopy analysis showed that He bubbles agglomerated along the vertical phase boundaries in morphologies with lateral and random domains of Cu and Mo. Nuclear Reaction Analysis (NRA) and nanoindentation results show He retention and hardness is morphology dependent.
