Abstract Scope |
Zirconium based alloys are widely used in the nuclear industry, due to their low capture cross section for thermal neutrons, and relatively good corrosion resistance. However, as a result of its HCP crystal structure, Zirconium has anisotropic mechanical properties and response to irradiation. In this study, using a single zirconium crystal of known crystallographic direction, micro-pillars were processed with focused ion beam in different orientations corresponding to different compression directions. The pillars were irradiated to 5 dpa with 1 MeV Kr ions, and subjected to in situ TEM compression testing at room temperature and 300C to determine the effects of anisotropy on the temperature and irradiation response of zirconium in terms of the mechanical properties. The suitability of the in-situ micro-mechanical testing to study mechanical property anisotropy is demonstrated and discussed. |
