Abstract Scope |
Accumulative roll bonding (ARB) process is an effective way of producing bulk nanocomposite materials that have a very high volume fraction of stable interfaces when composed of immiscible layers. Formed under extreme mechanical strains, these interfaces can trap point defects produced under irradiation making them very resistant to irradiation damage effects such irradiation hardening and void swelling. In this talk, I will present ion irradiation testing of two different ARB processed nanolayered composites (Cu/Nb and Zr/Nb) at very high irradiation doses (>200 dpa) and elevated temperatures (up to 600C). While layered stability is preserved in Cu/Nb, complete mixing of Zr/Nb layered structure is observed regardless of individual layer thickness. On the other hand no voids were observed in either of the systems. I will discuss the role of thermal spikes in layer stability under heavy ion irradiations. |
