Abstract

The excess volumes per unit grain-boundary area of nanocrystalline Pd and Ni thin films were measured by an efficacious method based on real time in situ x-ray diffraction measurements. The obtained large values for the grain-boundary excess volume reveal the background of surprising, yet unexplained observations of grain growth in nanocrystalline materials.
