Abstract Scope The evolution of the nanoporous structure of sintered silver during high temperature aging, ranging from 200C to 350C is investigated by in-situ Computed X-Ray Tomography. Investigations were performed on both pure sintered silver and specimens containing a silver/copper interface. It is shown that while pore evolution is driven by diffusion (Oswald ripening), the presence of an interface promotes faster growth kinetics until a deviation from Oswald ripening occurs. This evolution can be explained considering the conjugated effects of the thermal stresses and surface energy on the diffusion process. Preliminary finite elements modeling has been performed using the real microstructure in order to investigate on the relationship between mechanical loading and nanoporous structure evolution.
