| Abstract Scope |
Grain and phase boundaries are key microstructural elements in the management of radiation-induced defects in structural materials. This talk will describe investigations of interfaces in Zr-Nb alloys and their resistance to radiation damage. Atomistic simulation methods will be utilized to simulate these hcp-bcc interfaces. Our simulation technique is composed of two steps: (i) the creation of the three stacking orientations for Zr–Nb heterophase boundaries, and (ii) the introduction and evolution of irradiation defects in the vicinity of these boundaries. Defect evolution and intermixing at the interface will be discussed for the interfaces including the effect of changing Nb/Zr ratios. The evolution of interfacial structure will be studied in context of dose rate and primary knock-on atom energies. |
