Shear softening of grain boundaries in nanocrystalline Pd

Nanocrystalline materials are polycrystals with grain sizes L of the order of 10nm. Unlike conventional polycrystals, the volume fraction of matter in the core region of grain boundaries tends to approach the share of matter in the interior of the nanometer-sized grains since it scales as 1/L. The d...
