Metal degradation due to implanted helium (He) is a concern in nuclear energy applications. We investigate the size and distribution of He bubbles in Ta(Ti)/Zr(Ti) composites using transmission electron microscopy. He implanted composites are compared to both the unimplanted material as well as the individual constituents of the composite. Nano-scale He bubbles form in different quantities in the two components of this composite as well as at the curved Ta(Ti)/Zr(Ti) interfaces within the materials. We discuss the consequences of our findings for the development of radiation resistant materials with complex, hierarchical microstructures.
