[SY-I9] Quantifying point defect fluxes to interfaces and the role of interface structure
Invited
Point defect fluxes to and from interfaces can dominate the response of materials exposed to irradiation, their equilibration after thermal perturbation, and their sintering. However, little is known experimentally about how non-equilibrium point defect concentrations equilibrate, how their concentration gradients develop in the lattice, and the role of interface structure in affecting sink efficiency. This talk describes experimental approaches to probing these phenomena using localized tracer diffusion measurements and irradiaiton induced creep in model sample geometries.
