Abstract Scope |
The effects of Helium (He) accumulation in materials are of great interest to the nuclear community since He is produced from radionuclide transmutation and high energy neutron reactions. He is insoluble in almost all solids, and precipitates into nanometer sized bubbles which results in degradation of the mechanical properties of nuclear structural materials. Despite that He bubbles may significantly impact dynamic materials properties and processes, including high strain rate loading, studies along these lines are quite rare. This work investigates He bubbles in Titanium (Ti) samples with and without dynamic loading. Ti is implanted with He ions and then characterized using Transmission Electron Microscopy (TEM). Additional TEM investigation of He implanted and subsequent shock loaded samples is performed to characterize defect production as well as the restructuring and production of He bubbles resulting from shock loading, thereby addressing the dynamic properties of He bubbles. |
