| Abstract Scope |
Proton bombardment has become an important tool in the study of irradiation damage in reactor materials. Protons induce lattice damage at a far greater rate than observed during neutron irradiation, and do so with substantially less activation, but the technique does give rise to the implantation of a significant number of hydrogen atoms over time. An assessment of the potential for this hydrogen to impact microstructural evolution or mechanical properties requires an understanding of hydrogen transport and the precipitation and dissolution of any relevant hydride phases. Toward this end a computational simulation of hydrogen transport has been applied to a series of recent proton irradiation experiments conducted on Zircaloy-4 at the Michigan Ion Beam Laboratory. |
